ICL7621DESA

Overview

The ICL7621DESA-T is a dual general-purpose operational amplifier manufactured by Maxim Integrated, now part of Analog Devices. It features a rail-to-rail output and operates on supply voltages ranging from 2V to 16V single or ±1V to ±8V dual supplies. Key electrical parameters include a gain-bandwidth product of 480kHz, a slew rate of 0.016V/µs, an input bias current of 1pA, and an input offset voltage of 15mV. The device consumes 100µA of supply current per channel and functions within a temperature range of -40°C to 85°C. It is housed in an 8-SOIC surface-mount package.

Feature Summary

Ultra-low input bias current of 1pA suitable for high-impedance circuits
Rail-to-rail output capability maximizing dynamic range
Low power consumption with 100µA supply current per amplifier
Wide single or dual supply voltage operation

Applications

Long time constant integrators
Picoammeters
Low droop rate sample/hold amplifiers

Procurement Notes

Verify the obsolete status of this component before design finalization. Confirm that the specific suffix matches the required tape and reel packaging format. Ensure compatibility with existing PCB footprints for the 8-SOIC package. Check for available lifecycle management documentation from the manufacturer regarding end-of-life notifications.

Selection Notes

Select this component when ultra-low input bias current is critical for signal integrity. The CMOS architecture supports low-power battery-operated applications. Verify that the 480kHz bandwidth meets the system requirements. Consider the rail-to-rail output swing if driving loads close to supply rails.

Part Context

This device belongs to the ICL761X–ICL764X family of monolithic CMOS operational amplifiers. The family combines ultra-low input current with low-power operation over a wide supply voltage range. These amplifiers are designed for applications where input bias and offset currents are critical performance factors.
