ICL7632ECPE

Overview

The ICL7632ECPE is a CMOS operational amplifier featuring three independent circuits housed in a 16-pin PDIP package. It operates on a single supply voltage ranging from 2 V to 16 V with a typical supply current of 1 mA per channel. The device offers a slew rate of 1.6 V/µs and a gain-bandwidth product of 1.4 MHz. Input offset voltage is specified at 20 mV, with input bias current as low as 1 pA. It supports rail-to-rail output swing and functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• CMOS technology enables low power consumption with minimal supply current draw.
• Rail-to-rail output capability allows signal swings close to both supply rails.
• High input impedance characteristics provided by ultra-low input bias current.

Applications

• Battery-powered instrumentation systems requiring low quiescent current
• Portable medical devices utilizing single-supply operation
• Signal conditioning circuits for sensor interfaces

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status as legacy parts may have varying environmental declarations. Check for active obsolescence notices or last-time buy notifications before finalizing procurement plans.

Selection Notes

Select this component when designing single-supply applications that require rail-to-rail output performance without the complexity of dual supplies. Ensure the load capacitance requirements are met to maintain stability given the 1.4 MHz bandwidth. Verify that the 20 mV input offset voltage meets the precision requirements of the target application.

Part Context

This part belongs to the ICL76xx series of CMOS amplifiers, designed for low-power, single-supply operations. It serves as a general-purpose solution for analog signal processing where power efficiency and wide supply voltage flexibility are critical design constraints.

Replacement Considerations

The ICL7632ECPE+ is listed as a direct replacement option. Verify pin compatibility and electrical specifications match the original design requirements before substitution.
