ICL7631ECSE

Overview

The ICL7631ECSE is a CMOS operational amplifier featuring three independent circuits in a 16-SOIC package. It operates with a supply voltage range of 2 V to 16 V and draws 1 mA per channel. Key electrical parameters include a slew rate of 1.6 V/µs, a gain-bandwidth product of 1.4 MHz, and an input bias current of 1 pA. The device provides rail-to-rail output swing and has a minimum gain of 70 dB.

Feature Summary

• CMOS technology for low power consumption
• Rail-to-rail output capability
• High input impedance with 1 pA bias current

Applications

• Precision signal conditioning
• Sensor interface circuits
• Battery-powered instrumentation

Procurement Notes

Verify the specific suffix (SE vs SE+) against the manufacturer's current datasheet to confirm RoHS compliance and exact pinout compatibility. Confirm availability status as older revisions may be discontinued or subject to last-time buy notices from Analog Devices.

Selection Notes

Select this component when rail-to-rail output is required alongside ultra-low input bias current. Ensure the 1.4 MHz bandwidth meets system requirements. Verify that the 16-SOIC package fits the PCB layout constraints compared to the PDIP variant.

Part Context

Part of the ICL761x-ICL764x series of single/dual/triple/quad operational amplifiers. The ECSE designation indicates an industrial temperature range and SOIC packaging. It serves as a CMOS alternative to bipolar op-amps requiring high input impedance.

Replacement Considerations

Direct replacement: ICL7631ECSE+. Verify pinout compatibility before substitution.
