ICL7641CCPD

Overview

The ICL7641CCPD is a single operational amplifier from the ICL761X–ICL764X family of monolithic CMOS devices. It features ultra-low input current and low-power operation over a wide supply voltage range, supporting ±1V to ±8V dual supplies or 2V to 16V single supplies. The device utilizes a voltage-feedback architecture with internal frequency compensation. Its CMOS outputs swing to within millivolts of the supply rails, enabling rail-to-rail output capability.

Feature Summary

• Monolithic CMOS construction providing ultra-low input bias current
• Pin-selectable quiescent current options for power optimization
• Rail-to-rail output swing capability near supply voltages
• Internal frequency compensation for stable operation

Applications

• Low-power sensor signal conditioning
• Battery-operated instrumentation circuits
• High-impedance buffer stages
• Precision analog front-end processing

Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated channels. Confirm package integrity and pin alignment against the PDIP-14 specification. Review datasheet revisions for any parameter updates. Ensure storage conditions meet CMOS handling requirements to prevent electrostatic discharge damage during installation.

Selection Notes

Select this component when ultra-low input current and rail-to-rail output are required in a single-channel configuration. Compare against ICL7642 (quad) or ICL7643 (triple) variants if multiple amplifiers are needed. Verify that the voltage-feedback architecture meets bandwidth requirements for the specific application frequency range.

Part Context

Part of the ICL761X–ICL764X family of general-purpose CMOS operational amplifiers originally developed by Maxim Integrated, now under Analog Devices. This series is known for combining low power consumption with high precision. The ICL7641 specifically provides a single amplifier channel, distinguishing it from the dual, triple, and quad configurations available in the same product line.

Replacement Considerations

Check for ICL7641ECPD as an alternative variant within the same family. Verify pin compatibility and electrical specifications before substitution. Consult official manufacturer documentation for cross-reference recommendations.
