ICL7631CCPE

Overview

The ICL7631CCPE is a triple CMOS operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features three independent low-power amplifiers in a single package, designed for applications requiring minimal current consumption. The device operates within a supply voltage range of 1 V to 8 V (single) or 2 V to 16 V (dual). 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 16-PDIP through-hole package and supports commercial temperature ranges from 0°C to +70°C.

Feature Summary

• Triple-channel architecture integrating three independent CMOS operational amplifiers
• Low power operation with minimal quiescent current consumption
• Rail-to-rail output capability for maximum dynamic range
• CMOS input stage providing high input impedance

Applications

• Battery-powered instrumentation circuits
• Portable measurement devices
• Signal conditioning for low-frequency sensors
• Active filter implementations

Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance requirements as the specific CCPE variant may not meet current environmental standards. Check for direct replacements like the ICL7631ECPE+ if lead-free sourcing is mandatory. Validate package integrity upon receipt.

Selection Notes

Select this component for designs prioritizing ultra-low power consumption over high-speed performance. The 44 kHz bandwidth limits suitability for high-frequency signal processing. Ensure supply voltages remain within the specified 1 V to 8 V single-supply range to maintain optimal offset voltage and bias current characteristics.
