ICL7641BCWE

Overview

The ICL7641BCWE+ is a quad monolithic CMOS operational amplifier from the ICL761X–ICL764X family. It features an input offset voltage of 5mV and operates within a supply voltage range of ±1V to ±8V or single supplies from 2V to 16V. The device offers a unity-gain bandwidth of 44kHz, a slew rate of 0.016V/µs, and an input bias current of 50pA. It utilizes a 16-pin Wide SO package and supports a commercial operating temperature range of 0°C to +70°C.

Feature Summary

• Monolithic low-power CMOS design with ultra-low input bias current
• Wide supply voltage operation capability
• Rail-to-rail output swing performance

Applications

• Long-time constant integrators
• Picoammeters
• Low droop rate sample/hold amplifiers
• Battery-powered instruments

Procurement Notes

Verify the specific suffix 'BCWE+' against official manufacturer documentation to confirm the exact electrical grade (B), temperature range (C), and package type (WE). Confirm RoHS compliance status as indicated in the datasheet. Ensure compatibility with existing PCB footprints for the 16-pin Wide SO format before procurement.

Selection Notes

Select this component when multiple channels are required in a compact form factor. The B-grade specification provides a defined maximum input offset voltage suitable for precision applications. Consider the fixed quiescent current nature of the quad configuration compared to programmable single-channel variants.

Part Context

This part belongs to the ICL761X–ICL764X series of single, dual, triple, and quad operational amplifiers. The '4' designation indicates a quad configuration containing four independent amplifiers on a single die. This family is characterized by high input impedance and low power consumption.

Replacement Considerations

Check for ICL7641ECWE+ if extended temperature range is required. Verify pinout compatibility with other members of the ICL76XX family.
