| Order this document by MC33102/D Sleep-ModeTM Two-State, Micropower Operational Amplifier The MC33102 dual operational amplifier is an innovative design concept employing Sleep-Mode technology. Sleep-Mode amplifiers have two separate states, a sleepmode and an awakemode. In sleepmode, the amplifier is active and waiting for an input signal. When a signal is applied causing the amplifier to source or sink 160 A (typically) to the load, it will automatically switch to the awakemode which offers higher slew rate, gain bandwidth, and drive capability. * Two States: "Sleepmode" (Micropower) and "Awakemode" (High Performance) * Switches from Sleepmode to Awakemode in 4.0 s when Output Current Exceeds the Threshold Current (RL = 600 ) * Independent Sleepmode Function for Each Op Amp MC33102 DUAL SLEEP-MODE OPERATIONAL AMPLIFIER SEMICONDUCTOR TECHNICAL DATA * * * * * * Standard Pinouts - No Additional Pins or Components Required Sleepmode State - Can Be Used in the Low Current Idle State as a Fully Functional Micropower Amplifier Automatic Return to Sleepmode when Output Current Drops Below Threshold No Deadband/Crossover Distortion; as Low as 1.0 Hz in the Awakemode Drop-in Replacement for Many Other Dual Op Amps ESD Clamps on Inputs Increase Reliability without Affecting Device Operation D SUFFIX PLASTIC PACKAGE CASE 751 (SO-8) 8 1 P SUFFIX PLASTIC PACKAGE CASE 626 8 1 Sleep-Mode is a trademark of Motorola, Inc.

The two-state feature of this op amp enables it to conserve power during idle times, yet be powered up and ready for an input signal. Possible applications include laptop computers, automotive, cordless phones, baby monitors, and battery operated test equipment. Although most applications will require low power consumption, this device can be used in any application where better efficiency and higher performance is needed. The Sleep-ModeTM amplifier has two states; a sleepmode and an awakemode. In the sleepmode state, the amplifier is active and functions as a typical micropower op amp. When a signal is applied to the amplifier causing it to source or sink sufficient current (see Figure 13), the amplifier will automatically switch to the awakemode. See Figures 20 and 21 for transition times with 600 and 10 k loads. The awakemode uses higher drain current to provide a high slew rate, gain bandwidth, and output current capability. In the awakemode, this amplifier can drive 27 Vpp into a 600 load with VS = 15 V. An internal delay circuit is used to prevent the amplifier from returning to the sleepmode at every zero crossing. This delay circuit also eliminates the crossover distortion commonly found in micropower amplifiers. This amplifier can process frequencies as low as 1.0 Hz without the amplifier returning to sleepmode, depending on the load. The first stage PNP differential amplifier provides low noise performance in both the sleep and awake modes, and an all NPN output stage provides symmetrical source and sink AC frequency response. APPLICATIONS INFORMATION The MC33102 will begin to function at power supply voltages as low as VS = 1.0 V at room temperature. (At this voltage, the output voltage swing will be limited to a few hundred millivolts.) The input voltages must range between VCC and VEE supply voltages as shown in the maximum rating table. Specifically, allowing the input to go more negative than 0.3 V below VEE may cause product damage. Also, exceeding the input common mode voltage range on either input may cause phase reversal, even if the inputs are between VCC and VEE. When power is initially applied, the part may start to operate in the awakemode. This is because of the currents generated due to charging of internal capacitors. When this occurs and the sleepmode state is desired, the user will have to wait approximately 1.5 seconds before the device will switch back to the sleepmode. To prevent this from occurring, ramp the power supplies from 1.0 V to full supply. Notice that the device is more prone to switch into the awakemode when VEE is adjusted than with a similar change in VCC. The amplifier is designed to switch from sleepmode to awakemode whenever the output current exceeds a preset current threshold (ITH) of approximately 160 A. As a result, the output switching threshold voltage (VST) is controlled by the output loading resistance (RL). This loading can be a load resistor, feedback resistors, or both. Then: VST = (160 A) x RL Large valued load resistors require a large output voltage to switch, but reduce unwanted transitions to the awakemode. For instance, in cases where the amplifier is connected with a large closed loop gain (ACL), the input offset voltage (VIO) is multiplied by the gain at the output and could produce an output voltage exceeding VST with no input signal applied. Small values of RL allow rapid transition to the awakemode because most of the transition time is consumed slewing in the sleepmode until VST is reached (see Figures 20, 21). The output switching threshold voltage VST is higher for larger values of RL, requiring the amplifier to slew longer in the slower sleepmode state before switching to the awakemode. MOTOROLA ANALOG IC DEVICE DATA 11 MC33102 The transition time (ttr1) required to switch from sleep to awake mode is: ttr1 = tD = ITH (RL/SRsleepmode) Where: tD = Amplifier delay (<1.0 s) ITH = Output threshold current for = more transition (160 A) RL = Load resistance SRsleepmode = Sleepmode slew rate (0.16 V/s) Although typically 160 A, ITH varies with supply voltage and temperature. In general, any current loading on the output which causes a current greater than ITH to flow will switch the amplifier into the awakemode. This includes transition currents such as those generated by charging load capacitances. In fact, the maximum capacitance that can be driven while attempting to remain in the sleepmode is approximately 1000 pF. CL(max) = ITH/SRsleepmode = 160 A/(0.16 V/s) = 1000 pF Any electrical noise seen at the output of the MC33102 may also cause the device to transition to the awakemode. To minimize this problem, a resistor may be added in series with the output of the device (inserted as close to the device as possible) to isolate the op amp from both parasitic and load capacitance. The awakemode to sleepmode transition time is controlled by an internal delay circuit, which is necessary to prevent the amplifier from going to sleep during every zero crossing. This time is a function of supply voltage and temperature as shown in Figure 22. Gain bandwidth product (GBW) in both modes is an important system design consideration when using a sleepmode amplifier. The amplifier has been designed to obtain the maximum GBW in both modes. "Smooth" AC transitions between modes with no noticeable change in the amplitude of the output voltage waveform will occur as long as the closed loop gains (ACL) in both modes are substantially equal at the frequency of operation. For smooth AC transitions: (ACLsleepmode) (BW) < GBWsleepmode Where: ACLsleepmode = Closed loop gain in ACLsleepmode = the sleepmode BW = The required system bandwidth BW = or operating frequency TESTING INFORMATION To determine if the MC33102 is in the awakemode or the sleepmode, the power supply currents (ID+ and ID-) must be measured. When the magnitude of either power supply current exceeds 400 A, the device is in the awakemode. When the magnitudes of both supply currents are less than 400 A, the device is in the sleepmode. Since the total supply current is typically ten times higher in the awakemode than the sleepmode, the two states are easily distinguishable. The measured value of ID+ equals the ID of both devices (for a dual op amp) plus the output source current of device A and the output source current of device B. Similarly, the measured value of ID- is equal to the ID- of both devices plus the output sink current of each device. Iout is the sum of the currents caused by both the feedback loop and load resistance. The total Iout needs to be subtracted from the measured ID to obtain the correct ID of the dual op amp. An accurate way to measure the awakemode Iout current on automatic test equipment is to remove the Iout current on both Channel A and B. Then measure the ID values before the device goes back to the sleepmode state. The transition will take typically 1.5 seconds with 15 V power supplies. The large signal sleepmode testing in the characterization was accomplished with a 1.0 M load resistor which ensured the device would remain in sleepmode despite large voltage swings. 12 MOTOROLA ANALOG IC DEVICE DATA MC33102 OUTLINE DIMENSIONS D SUFFIX PLASTIC PACKAGE CASE 751-05 (SO-8) ISSUE R A 8 D 5 C E 1 4 H 0.25 M B M h B C e A SEATING PLANE X 45 _ NOTES: 1.
