ICL7631CCPE

Overview

The ICL7631CCPE is a triple CMOS low-power operational amplifier manufactured by Analog Devices under the Maxim Integrated brand. It features three independent amplifiers in a single package, designed for applications requiring minimal power consumption. The device operates on a supply voltage range of 1V to 8V or 2V to 16V depending on configuration. Key electrical parameters include a gain-bandwidth product of 44 kHz, a slew rate of 16 mV/us, and an input bias current of 50 pA. It utilizes a PDIP-16 through-hole package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Triple channel architecture providing three independent low-power amplifiers in one component
• CMOS technology enabling ultra-low quiescent current operation for battery-powered systems
• Wide single-supply voltage compatibility supporting flexible power design options

Applications

• Battery-operated instrumentation circuits
• Low-power signal conditioning stages
• Portable measurement devices

Procurement Notes

Verify component authenticity as this part is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or surplus suppliers. Ensure the PDIP-16 package matches your PCB footprint requirements. Check RoHS compliance status if required for specific manufacturing standards. Validate that the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when multiple low-power amplification channels are needed without increasing board space. Consider the 44 kHz bandwidth limit for high-speed applications. Evaluate the 10 mV input offset voltage against precision requirements. Compare power consumption benefits against newer CMOS op-amp alternatives with similar pinouts.

Part Context

This part belongs to the ICL7631C series of triple operational amplifiers. It shares functional similarities with other low-power CMOS op-amps but offers distinct triple-channel integration. The device represents legacy analog design solutions from the Maxim Integrated portfolio now managed by Analog Devices.

Replacement Considerations

Check for direct pin-compatible replacements from Analog Devices or third-party manufacturers. Verify that substitute parts maintain the same 44 kHz bandwidth and low power characteristics. Ensure alternative packages match the PDIP-16 form factor.
