+ DATASHEET ICL7621 FN3403 Rev.5.00 Dual, Low Power CMOS Operational Amplifiers Mar 4, 2010 The ICL761X/762X series is a family of monolithic CMOS Features operational amplifiers. These devices provide the designer Wide Operating Voltage Range . 1V to 8V with high performance operation at low supply voltages and 12 High Input Impedance .10 selectable quiescent currents. They are an ideal design tool when ultra low input current and low power dissipation are Input Current Lower Than BIFETs . 1pA (Typ) desired. Output Voltage Swing V+ and V- The basic amplifier will operate at supply voltages ranging Available as Duals (Refer to ICL7611 for Singles) from 1V to 8V, and may be operated from a single Lithium Low Power Replacement for Many Standard Op Amps cell. The output swing ranges to within a few millivolts of the supply voltages. Applications The quiescent supply current of these amplifiers is set to Portable Instruments 100A at the factory. This results in power consumption as Telephone Headsets low as 200W per amplifier. Hearing Aid/Microphone Amplifiers Of particular significance is the extremely low (1pA) input Meter Amplifiers 12 current, input noise current of 0.01pA/ Hz, and 10 input Medical Instruments impedance. These features optimize performance in very High Impedance Buffers high source impedance applications. The inputs are internally protected. Outputs are fully Pinouts ICL7621 protected against short circuits to ground or to either supply. (8 LD PDIP, SOIC) TOP VIEW Because of the low power dissipation, junction temperature rise and drift are quite low.

They are not intended for use in Reflow solder processing applications. NOTES: 1. Add -T suffix for tape and reel. Please refer to TB347 for details on reel specifications. 2. These Intersil Pb-free plastic packaged products employ special Pb- free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
