ICL7631ECSE+

Overview

The ICL7631ECSE+ is a CMOS operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features three independent circuits housed in a 16-pin SOIC package. The device operates within a supply voltage range of 2 V to 16 V, with a typical operating voltage of 5 V. Key electrical specifications include a maximum input offset voltage of 20 mV, an input bias current of 1 pA, and a gain-bandwidth product of 1.4 MHz. The unit supports a slew rate of 1.6 V/µs and draws approximately 1 mA of supply current per channel. It functions as a rail-to-rail output amplifier suitable for commercial temperature ranges.

Feature Summary

• CMOS technology enabling low power consumption and high input impedance
• Rail-to-rail output capability for maximum dynamic range
• Integrated shutdown functionality for power management

Applications

• Battery-powered instrumentation systems
• Active filtering circuits
• Signal conditioning stages

Procurement Notes

Verify the specific suffix 'ECSE+' against official manufacturer documentation to confirm pinout compatibility and RoHS status. Ensure the selected variant matches the required package type and thermal characteristics for the target application environment.

Selection Notes

Select this component when a low-power, rail-to-rail output amplifier is required for single-supply applications. Consider the 1.4 MHz bandwidth and 1.6 V/µs slew rate for moderate-speed signal processing tasks requiring minimal quiescent current.

Part Context

This part belongs to the ICL7631 series of CMOS operational amplifiers. It provides a cost-effective solution for general-purpose analog signal processing where low power and wide supply voltage operation are critical design constraints.

Replacement Considerations

Direct replacement options may include other CMOS op-amps with similar rail-to-rail output capabilities and comparable bandwidth specifications from the same manufacturer family.
