DATASHEET ICL711, ICL71 1.MHz, Low Power CMOS Operational Amplifiers The ICL71X series is a family of CMOS operational amplifiers. These devices provide the designer with high performance operation at low supply voltages and selectable quiescent currents, and are an ideal design tool when ultra low input current and low power dissipation are desired. The basic amplifier will operate at supply voltages ranging from 1V to V, and may be operated from a single Lithium cell. A unique quiescent current programming pin allows setting of standby current to 1mA, A, or A, with no external components. This results in power consumption as low as W. The output swing ranges to within a few millivolts of the supply voltages. Of particular significance is the extremely low (1pA) input current, input noise current of.1pa/ Hz, and 1 input impedance. These features optimize performance in very high source impedance applications. The inputs are internally protected. Outputs are fully protected against short circuits to ground or to either supply. AC performance is excellent, with a slew rate of 1.V/ s, and unity gain bandwidth of Hz at. Features FN919 Rev 9.

Application Information Static Protection All devices are static protected by the use of input diodes. However, strong static fields should be avoided, as it is possible for the strong fields to cause degraded diode junction characteristics, which may result in increased input leakage currents. Latchup Avoidance Junctionisolated CMOS circuits employ configurations which produce a parasitic layer (PNPN) structure. The layer structure has characteristics similar to an SCR, and under certain circumstances may be triggered into a low impedance state resulting in excessive supply current. To avoid this condition, no voltage greater than.3v beyond the supply rails may be applied to any pin. In general, the op amp supplies must be established simultaneously with, or before any input signals are applied. If this is not possible, the drive circuits must limit input current flow to ma to prevent latchup. Choosing the Proper I Q The ICL711 and ICL71 have a similar I Q setup scheme, which allows the amplifier to be set to nominal quiescent currents of A, A or 1mA. These current settings change only very slightly over the entire supply voltage range. The ICL711 and ICL71 have an external I Q control terminal, permitting user selection of quiescent current. To set the I Q connect the I Q terminal as follows: I Q = A I Q pin to V I Q = A I Q pin to ground. If this is not possible, any voltage from V. to V. can be used. I Q pin to V NOTE: The output current available is a function of the quiescent current setting. For maximum peaktopeak output voltage swings into low impedance loads, IQ of 1mA should be selected. Output Stage and Load Driving Considerations Each amplifiers quiescent current flows primarily in the output stage. This is approximately 7% of the I Q settings. This allows output swings to almost the supply rails for output loads of, k, and k, using the output stage in a highly linear class A mode. In this mode, crossover distortion is avoided and the voltage gain is maximized. However, the output stage can also be operated in Class AB for higher output currents. (See graphs under Typical Operating Characteristics). During the transition from Class A to Class B operation, the output transfer characteristic is nonlinear and the voltage gain decreases. Input Offset Nulling Offset nulling may be achieved by connecting a 5k pot between the BAL terminals with the wiper connected to V. At quiescent currents of 1mA and A the nulling range provided is adequate for all V OS selections; however with I Q = A, nulling may not be possible with higher values of V OS. Frequency Compensation The ICL711 and ICL71 are internally compensated, and are stable for closed loop gains as low as unity with capacitive loads up to pf. Extended Common Mode Input Range The ICL71 incorporates additional processing which allows the input CMVR to exceed each power supply rail by.1v for applications where V SUPP 1.5V. For those applications where V SUPP 1.5V the input CMVR is limited in the positive direction, but may exceed the negative supply rail by.1v in the negative direction (e.g., for V SUPPLY = 1V, the input CMVR would be.v to 1.1V). Operation At V SUPPLY = 1V Operation at V SUPPLY = 1V is guaranteed at I Q = A for A and B grades only. Output swings to within a few millivolts of the supply rails are achievable for R L. Guaranteed input CMVR is.v minimum and typically.9v to.7v at V SUPPLY = 1V. For applications where greater common mode range is desirable, refer to the description of ICL71 above. Typical Applications The user is cautioned that, due to extremely high input impedances, care must be exercised in layout, construction, board cleanliness, and supply filtering to avoid hum and noise pickup. Note that in no case is I Q shown. The value of I Q must be chosen by the designer with regard to frequency response and power dissipation. V IN V IN k ICL71 R L k FIGURE 1.
