FN3403 Rev.5.00 Mar 4, 2010 ICL7621 Dual, Low Power CMOS Operational Amplifiers DATASHEETThe ICL761X/762X series is a family of monolithic CMOS operational amplifiers. These devices provide the designer with high performance operation at low supply voltages and selectable quiescent currents. They 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 8V, and may be operated from a single Lithium cell. The output swing ranges to within a few millivolts of the supply voltages. The quiescent supply current of these amplifiers is set to 100µA at the factory. This results in power consumption as low as 200µW per amplifier. Of particular significance is the extremely low (1pA) input current, input noise current of 0.01pA/Hz, and 1012 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. Because of the low power dissipation, junction temperature rise and drift are quite low. Applications utilizing these features may include stable instruments, extended life designs, or high density packages.

ICL7621Application 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 Junction-isolated CMOS circuits employ configurations which produce a parasitic 4-layer (PNPN) structure. The 4-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 0.3V 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 2mA to prevent latchup. Choosing the Proper IQ Each device in the ICL76XX family has a similar IQ setup scheme, which allows the amplifier to be set to nominal quiescent currents of 10µA, 100µA or 1mA. These current settings change only very slightly over the entire supply voltage range. The ICL7611/12 have an external IQ control terminal, permitting user selection of each amplifiers’ quiescent current. The ICL7621 has a fixed IQ setting of 100µA. Output Stage and Load Driving Considerations Each amplifiers’ quiescent current flows primarily in the output stage. This is approximately 70% of the IQ settings. This allows output swings to almost the supply rails for output loads of 1M, 100k, and 10k, 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 in “Typical Performance Curves” beginning on page 6). During the transition from Class A to Class B operation, the output transfer characteristic is nonlinear and the voltage gain decreases. Frequency Compensation The ICL76XX are internally compensated, and are stable for closed loop gains as low as unity with capacitive loads up to 100pF. 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.
