ICL7621DESA+

Overview

The ICL7621DESA+ is a dual-channel monolithic CMOS operational amplifier manufactured by Analog Devices/Maxim Integrated. It operates within a supply voltage range of ±1V to ±8V (2V to 16V single supply). The device features an input bias current of 50pA maximum, an input offset voltage of 15mV, and a gain-bandwidth product of 44kHz. It utilizes an 8-pin SOIC surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

Monolithic CMOS design providing ultra-low input bias current for high-impedance source applications
Rail-to-rail output capability allowing signal swing to within millivolts of the supply voltages
Wide supply voltage operation supporting both single and dual power configurations

Applications

Long-time constant integrators
Picoammeters
Low-leakage amplifiers
Low-frequency active filters

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices prior to procurement. Ensure the ordering suffix matches the required temperature grade and packaging specifications for the target application environment.

Selection Notes

Select this component when low input bias current and rail-to-rail output are critical requirements. Verify that the 44kHz bandwidth meets the signal frequency needs. Consider the fixed quiescent current of the dual configuration compared to programmable options in the single-channel variants of the same family.

Part Context

This part belongs to the ICL761X–ICL764X family of precision operational amplifiers. The 'D' designation indicates a 15mV maximum input offset voltage, while the 'E' suffix specifies the extended industrial temperature range. The 'SA' code identifies the 8-pin Small Outline package format.
