AD8207 rev. 0 | page 10 of 16 theory of operation the AD8207 is a single-supply, zero drift, difference amplifier that uses a unique architecture to accurately amplify small differential current shunt voltages in the presence of rapidly changing common-mode voltage. in typical applications, the AD8207 is used to measure current by amplifying the voltage across a shunt resistor connected to its inputs. the AD8207 includes a zero-drift amplifier, a precision resistor network, a common-mode control amplifier, and a precision reference (see figure 25 ). a set of precision-trimmed resistors make up the network that attenuates the input common-mode voltage to within the supply range of the amplifier, in this case with a ratio of 20/1. this attenuation ensures that when the input pins are externally at the common-mode extremes of ?4 v and +65 v, the actual voltage at the inputs of the main amplifier is still within the supply range. the input resistor network also attenuates normal (differential) mode voltages. therefore, the total internal gain of the AD8207 is set to 400 v/v to provide a total system gain of 20 v/v. total gain (v/v) = 1/20 (v/v) 400 (v/v) = 20 v/v the AD8207 is designed to provide excellent common-mode rejection, even with pwm common-mode inputs that can change at very fast rates, for example, 1 v/ns. an internal common-mode control amplifier is used to maintain the input common mode of the main amplifier at 3.5 v (with 5 v supply), and therefore eliminates the negative effects of such fast- changing external common-mode variations. the AD8207 features an input offset drift of less than 500 nv/c. this performance is achieved through a novel zero-drift architecture that does not compromise band- width, which is typically rated at 150 khz. the reference inputs, v ref 1 and v ref 2, are tied through 100 k resistors to the positive input of the main amplifier, which allows the output offset to be adjusted anywhere in the output operating range. the gain is 1 v/v from the reference pins to the output when the reference pins are used in parallel. when the pins are used to divide the supply, the gain is 0.5 v/v. the AD8207 offers breakthrough performance without compromising any of the robust application needs typical of solenoid or motor control. the part rejects pwm input common-mode voltages, while the zero-drift architecture yields the lowest offset and offset drift performance on the market. zero-drift amplifier AD8207 common-mode control amplifier 3.5v/2.2v ref 60k? 120k ? shunt 120k ? +in gnd ?in out v ref 1 v ref 2 60k? 9k? 50k? 6k ? 6k? 09160-025 100k? 100k? 100k? 100k? 100k ? figure 25. simplified schematic
AD8207 rev. 0 | page 11 of 16 power supply adjustment 3.3 v to 4.5 v supply operation the AD8207 can operate with a single-supply voltage as low as 3.3 v to 4.5 v. this mode of operation is achieved by con- necting the range pin (pin 4) to the supply (see figure 26 ). it is recommended that an external resistor be placed in series from the range pin to the supply. this resistor can be a typical 5 k 1% resistor. 1 2 3 4 8 7 6 5 AD8207 top view (not to scale) 3.3v 3.3v out shunt 09160-010 figure 26. 3.3 v supply operation note that in this mode of operation, the common-mode range of the AD8207 is limited to ?4 v to +35 v. the output and reference input ranges are limited to the supply of the part. the user can have a 4.5 v supply and connect the range pin from 3.3 v to 4.5 v. alternatively, the user can connect the range pin as high as 4.5 v, with the supply from 3.3 v to 4.5 v. 4.5 v to 5.5 v supply operation in most applications, the AD8207 operates with a single 5 v supply. in this mode, the operating input common-mode range of the AD8207 is rated from ?4 v to +65 v. to operate the device with a 5 v supply (includes 4.5 v to 5.5 v), connect the range pin (pin 4) to logic low, or gnd, as shown in figure 27 . 1 2 3 4 8 7 6 5 AD8207 top view (not to scale) 5v out shunt 09160-011 figure 27. 5 v supply bidirectional operation the output and reference input ranges are limited to the supply voltage used. with a supply voltage from 4.5 v to 5.5 v, the range pin (pin 4) should be connected to gnd to achieve the maximum input common-mode range specification of ?4 v to +65 v.
AD8207 rev. 0 | page 12 of 16 output offset adjustment the output of the AD8207 can be adjusted for unidirectional or bidirectional operation. unidirectional operation unidirectional operation allows the AD8207 to measure currents through a resistive shunt in one direction. the basic modes for unidirectional operation are ground referenced output mode and v+ referenced output mode. for unidirectional operation, the output can be set at the negative rail (near ground) or at the positive rail (near v+) when the differential input is 0 v. the output moves to the opposite rail when a correct polarity differential input voltage is applied. in this case, full scale is approximately 250 mv for a 5 v supply or 165 mv for a 3.3 v supply. the required polarity of the differential input depends on the output voltage setting. if the output is set at the positive rail, the input polarity must be negative to move the output down. if the output is set at ground, the polarity must be positive to move the output up. ground referenced output mode when using the AD8207 in the ground referenced output mode, both reference inputs are tied to ground, which causes the output to sit at the negative rail when there are 0 differential volts at the input (see figure 28 ). ref zero drift +in ?in out v+ gnd v ref 1 v ref 2 range AD8207 5 v 09160-012 figure 28. ground referenced output mode, v+ = 5 v table 4. ground referenced output v in (referred to ?in) v o v+ = 5 v 0 v 0.02 v 250 mv 4.95 v v+ = 3.3 v 0 v 0.02 v 165 mv 3.25 v v+ referenced output mode the v+ referenced output mode is set when both reference pins are tied to the positive supply. this mode is typically used when the diagnostic scheme requires detection of the amplifier and the wiring before power is applied to the load (see figure 29 ). range ref zero drift +in ?in out v+ gnd v ref 1 v ref 2 AD8207 5 v 09160-013 figure 29. v+ referenced output mode, v+ = 5 v table 5. v+ referenced output v in (referred to ? in) v o v+ = 5 v 0 v 4.95 v ?250 mv 0.02 v v+ = 3.3 v 0 v 3.25 v ?165 mv 0.02 v bidirectional operation bidirectional operation allows the AD8207 to measure currents through a resistive shunt in two directions. in this case, the output is set anywhere within the output range. typically, it is set at half scale for equal range in both directions. in some cases, however, it is set at a voltage other than half scale when the bidirectional current is asymmetrical. table 6. v o = (v+/2) with v in = 0 v v in (referred to ?in) v o v+ = 5 v +100 mv 4.5 v ?100 mv 0.5 v v+ = 3.3 v +67.5 mv 3 v ?67.5 mv 0.3 v adjusting the output is accomplished by applying voltages to the reference inputs. v ref 1 and v ref 2 are tied to internal resistors that connect to an internal offset node. there is no operational difference between the pins.
AD8207 rev. 0 | page 13 of 16 external referenced output tying both reference pins together and to an external reference produces an output equal to the reference voltage when there is no differential input (see figure 30 ). the output moves down from the reference voltage when the input is negative, relative to the ?in pin, and up when the input is positive, relative to the ?in pin. the reference pins are connected to the positive input of the main amplifier via precision-trimmed 100 k resistors. therefore, it is recommended that a low impedance voltage is always be used to set the reference voltage. if external resistors are connected directly to the v ref 1 and v ref 2 pins, there will be a mismatch with the internal trimmed resistors, leading to offset gain accuracy reduction. range v+ 5 v ref +in ?in out voltage reference gnd AD8207 zero drift v ref 1 v ref 2 2.5v 09160-014 figure 30. external referenced output, v+ = 5 v splitting the supply by tying one reference pin to v+ and the other to the ground pin, the output is set at half of the supply when there is no dif- ferential input (see figure 31 ). the benefit is that no external reference is required to offset the output for bidirectional current measurement. this creates a midscale offset that is ratiometric to the supply, which means that if the supply increases or decreases, the output remains at half the supply. for example, if the supply is 5.0 v, the output is at half scale, or 2.5 v. if the supply increases by 10% (to 5.5 v), the output goes to 2.75 v. range v+ 5 v ref +in ?in out gnd AD8207 zero drift v ref 1 v ref 2 09160-015 figure 31. splitting the supply, v+ = 5 v splitting an external reference in figure 32 , an external reference is divided by 2 with an accuracy of approximately 0.5% by connecting one v ref pin to ground and the other v ref pin to the reference (see figure 32 ). v+ 5 v ref +in ?in out voltage reference gnd AD8207 zero drift v ref 1 v ref 2 5v 09160-016 range figure 32. splitting an external reference, v+ = 5 v
AD8207 rev. 0 | page 14 of 16 applications information motor control 3-phase motor control the AD8207 is ideally suited for monitoring current in 3-phase motor applications. the 150 khz typical bandwidth of the AD8207 allows for instantaneous current monitoring. additionally, the typical low offset drift of 500 nv/c means that the measurement error between the two motor phases will be at a minimum over temperature. the AD8207 rejects pwm input common- mode voltages in the range of ?4 v to +65 v (with a 5 v supply). monitoring the current on the motor phase allows for sampling of the current at any point and allows for diagnostic information such as a short to gnd and battery. refer to figure 34 for a typical phase current measurement setup with the AD8207. h-bridge motor control another typical application for the AD8207 is as part of the control loop in h-bridge motor control. in this case, the shunt resistor is placed in the middle of the h-bridge (see figure 33 ) so that it can accurately measure current in both directions by using the shunt available at the motor. this is a better solution than a ground referenced op amp because ground is not typically a stable reference voltage in this type of application. the instability of the ground reference causes inaccuracies in the measurements that could be made with a simple ground referenced op amp. the AD8207 measures current in both directions as the h-bridge switches and the motor changes direction. the output of the AD8207 is config- ured in an external referenced bidirectional mode (see the bidirectional operation section).

AD8207 rev. 0 | page 15 of 16 solenoid control high-side current sense with a low-side switch other typical applications for the AD8207 include current monitoring for pwm control of solenoid openings. typical applications include hydraulic valve control, diesel injection control, and actuator control. in figure 35 , the pwm control switch is ground referenced. an inductive load (solenoid) is tied to a power supply. a resistive shunt is placed between the switch and the load (see figure 35 ). an advantage of placing the shunt on the high side is that the entire current, including the recirculation current, can be measured because the shunt remains in the loop when the switch is off. in addition, diagnostics capabilities are enhanced because shorts to ground can be detected with the shunt on the high side. in this circuit configuration, when the switch is closed, the common-mode voltage moves down to near the negative rail. when the switch is opened, the voltage reversal across the inductive load causes the common-mode voltage to be held one diode drop above the battery by the clamp diode.
