LT6200/LT6200-5 LT6200-10/LT6201 165MHz, Rail-to-Rail Input and Output, 0.95nV/Hz Low Noise, Op Amp Family FEATURES
n n
DESCRIPTION
The LT(R)6200/LT6201 are single and dual ultralow noise, rail-to-rail input and output unity gain stable op amps that feature 0.95nV/Hz noise voltage. These amplifiers combine very low noise with a 165MHz gain bandwidth, 50V/s slew rate and are optimized for low voltage signal conditioning systems. A shutdown pin reduces supply current during standby conditions and thermal shutdown protects the part from overload conditions. The LT6200-5/LT6200-10 are single amplifiers optimized for higher gain applications resulting in higher gain bandwidth and slew rate. The LT6200 family maintains its performance for supplies from 2.5V to 12.6V and are specified at 3V, 5V and 5V. For compact layouts the LT6200/LT6200-5/LT6200-10 are available in the 6-lead ThinSOTTM and the 8-pin SO package. The dual LT6201 is available in an 8-pin SO package with standard pinouts as well as a tiny, dual fine pitch leadless package (DFN). These amplifiers can be used as plug-in replacements for many high speed op amps to improve input/output range and noise performance.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime
Note 2: Inputs are protected by back-to-back diodes. If the differential input voltage exceeds 0.7V, the input current must be limited to less than 40mA. This parameter is guaranteed to meet specified performance through design and/or characterization. It is not 100% tested.

LT6200/LT6200-5 LT6200-10/LT6201 ELECTRICAL CHARACTERISTICS
Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. The LT6201 in the DD package is limited by power dissipation to VS 5V, 0V over the commercial temperature range only. Note 4: The LT6200C/LT6200I and LT6201C/LT6201I are guaranteed functional over the temperature range of -40C and 85C (LT6201DD excluded). Note 5: The LT6200C/LT6201C are guaranteed to meet specified performance from 0C to 70C. The LT6200C/LT6201C are designed, characterized and expected to meet specified performance from -40C to 85C, but are not tested or QA sampled at these temperatures. The LT6200I is guaranteed to meet specified performance from -40C to 85C. Note 6: Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 7: Output voltage swings are measured between the output and power supply rails. Note 8: This parameter is not 100% tested. Note 9: Full-power bandwidth is calculated from the slew rate: FPBW = SR/2VP Note 10: Thermal resistance varies depending upon the amount of PC board metal attached to the V- pin of the device. JA is specified for a certain amount of 2oz copper metal trace connecting to the V- pin as described in the thermal resistance tables in the Application Information section. Note 11: Matching parameters on the LT6201 are the difference between the two amplifiers. CMRR and PSRR match are defined as follows: CMRR and PSRR are measured in V/V on the identical amplifiers. The difference is calculated in V/V. The result is converted to dB. Note 12: There are reverse biased ESD diodes on all inputs and outputs, as shown in Figure 1. If these pins are forced beyond either supply, unlimited current will flow through these diodes. If the current is transient in nature and limited to less than 30mA, no damage to the device will occur.

LT6200/LT6200-5 LT6200-10/LT6201 APPLICATIONS INFORMATION
Amplifier Characteristics Figure 1 shows a simplified schematic of the LT6200 family, which has two input differential amplifiers in parallel that are biased on simultaneously when the common mode voltage is at least 1.5V from either rail. This topology allows the input stage to swing from the positive supply voltage to the negative supply voltage. As the common mode voltage swings beyond VCC - 1.5V, current source I1 saturates and current in Q1/Q4 is zero. Feedback is maintained through the Q2/Q3 differential amplifier, but with an input gm reduction of one-half. A similar effect occurs with I2 when the common mode voltage swings within 1.5V of the negative rail. The effect of the gm reduction is a shift in the VOS as I1 or I2 saturate. Input bias current normally flows out of the "+" and "-" inputs. The magnitude of this current increases when the input common mode voltage is within 1.5V of the negative rail, and only Q1/Q4 are active. The polarity of this current reverses when the input common mode voltage is within 1.5V of the positive rail and only Q2/Q3 are active. The second stage is a folded cascode and current mirror that converts the input stage differential signals to a single ended output. Capacitor C1 reduces the unity cross frequency and improves the frequency stability without degrading the gain bandwidth of the amplifier. The differential drive generator supplies current to the output transistors that swing from rail-to-rail.

The LT6200-5/LT6200-10 are decompensated op amps for higher gain applications. These amplifiers maintain identical DC specifications with the LT6200, but have a reduced Miller compensation capacitor CM. This results in a significantly higher slew rate and gain bandwidth product. Input Protection There are back-to-back diodes, D1 and D2, across the + and - inputs of these amplifiers to limit the differential input voltage to 0.7V. The inputs of the LT6200 family do not have internal resistors in series with the input transistors. This technique is often used to protect the input devices from overvoltage that causes excessive currents to flow. The addition of these resistors would significantly degrade the low noise voltage of these amplifiers. For instance, a 100 resistor in series with each input would generate 1.8nV/Hz of noise, and the total amplifier noise voltage would rise from 0.95nV/Hz to 2.03nV/Hz. Once the input differential voltage exceeds 0.7V, steady-state current conducted though the protection diodes should be limited to 40mA. This implies 25 of protection resistance per volt of continuous overdrive beyond 0.7V. The input diodes are rugged enough to handle transient currents due to amplifier slew rate overdrive or momentary clipping without these resistors.

Figure 2 shows the input and output waveforms of the LT6200 driven into clipping while connected in a gain of AV = 1. In this photo, the input signal generator is clipping at 35mA, and the output transistors supply this generator current through the protection diodes. Power Dissipation The LT6200 combines high speed with large output current in a small package, so there is a need to ensure that the die's junction temperature does not exceed 150C. The LT6200 is housed in a 6-lead TSOT-23 package. The package has the V - supply pin fused to the lead frame to enhance the thermal conductance when connecting to a ground plane or a large metal trace. Metal trace and plated through-holes can be used to spread the heat generated by the device to the backside of the PC board. For example, on a 3/32" FR-4 board with 2oz copper, a total of 270mm2 connects to Pin 2 of the LT6200 (in a TSOT-23 package) bringing the thermal resistance, JA, to about 135C/W. Without an extra metal trace beside the power line connecting to the V - pin to provide a heat sink, the thermal resistance will be around 200C/W. More information on thermal resistance with various metal areas connecting to the V - pin is provided in Table 1.

ESD The LT6200 has reverse-biased ESD protection diodes on all inputs and outputs, as shown in Figure 1. If these pins are forced beyond either supply, unlimited current will flow through these diodes. If the current is transient and limited to 30mA or less, no damage to the device will occur. Noise The noise voltage of the LT6200 is equivalent to that of a 56 resistor--and for the lowest possible noise, it is desirable to keep the source and feedback resistance at or below this value (i.e., RS + RG //RFB 56). With RS + RG //RFB = 56 the total noise of the amplifier is: en = (0.95nV)2 + (0.95nV)2 = 1.35nV. Below this resistance value the amplifier dominates the noise, but in the resistance region between 56 and approximately 6k, the noise is dominated by the resistor thermal noise. As the total resistance is further increased, beyond 6k, the noise current multiplied by the total resistance eventually dominates the noise. For a complete discussion of amplifier noise, see the LT1028 data sheet.
Junction temperature TJ is calculated from the ambient temperature TA and power dissipation PD as follows: TJ = TA + (PD * JA) The power dissipation in the IC is the function of the supply voltage, output voltage and the load resistance. For a given supply voltage, the worst-case power dissipation PD(MAX) occurs at the maximum quiescent supply current and at the output voltage which is half of either supply voltage (or the maximum swing if it is less than half the supply voltage). PD(MAX) is given by: PD(MAX) = (VS * IS(MAX)) + (VS /2)2/RL Example: An LT6200 in TSOT-23 mounted on a 2500mm2 area of PC board without any extra heat spreading plane connected to its V - pin has a thermal resistance of

200C/W, JA. Operating on 5V supplies driving 50 loads, the worst-case power dissipation is given by: PD(MAX) = (10 * 23mA) + (2.5)2/50 = 0.23 + 0.125 = 0.355W The maximum ambient temperature that the part is allowed to operate is: TA = TJ - (PD(MAX) * 200C/W) = 150C - (0.355W * 200C/W) = 79C To operate the device at a higher ambient temperature, connect more metal area to the V - pin to reduce the thermal resistance of the package, as indicated in Table 1. DD Package Heat Sinking The underside of the DD package has exposed metal (4mm2) from the lead frame where the die is attached. This provides for the direct transfer of heat from the die junction to printed circuit board metal to help control the maximum operating junction temperature. The dual-in-line pin arrangement allows for extended metal beyond the ends of the package on the topside (component side) of The LT6200 amplifier family has thermal shutdown to protect the part from excessive junction temperature. The amplifier will shut down to approximately 1.2mA supply current per amplifier if the maximum temperature is exceeded. The LT6200 will remain off until the junction temperature reduces to about 135C, at which point the amplifier will return to normal operation. a PCB. Table 2 summarizes the thermal resistance from the die junction-to-ambient that can be obtained using various amounts of topside metal (2oz copper) area. On multilayer boards, further reductions can be obtained using additional metal on inner PCB layers connected through vias beneath the package.
