ICL7631ECPE

Overview

The ICL7631ECPE is a CMOS operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features three independent circuits in a 16-PDIP package. The device operates with a supply voltage range of 2 V to 16 V and draws 1 mA per channel. Key electrical parameters include a gain-bandwidth product of 1.4 MHz, a slew rate of 1.6 V/µs, an input bias current of 1 pA, and an input offset voltage of 20 mV. It supports full-swing output and functions within a temperature range of 0°C to 70°C.

Feature Summary

• CMOS technology for low power consumption
• Three independent amplifier circuits
• Full-swing output capability
• Low input bias current

Applications

• General-purpose analog signal processing
• Battery-powered instrumentation
• Sensor interface circuits

Procurement Notes

Verify the component status as discontinued or obsolete before procurement planning. Confirm that the direct replacement part number ICL7631ECPE+ meets all functional requirements. Check RoHS compliance status, as the original may not meet current environmental standards. Ensure the 16-DIP package footprint matches the target PCB design constraints.

Selection Notes

Select this component when a low-power, multi-channel CMOS amplifier is required. The 1.4 MHz bandwidth and 1.6 V/µs slew rate suit moderate-speed applications. Verify that the 2 V minimum supply voltage aligns with the system power architecture. Consider the 16-pin DIP package for through-hole assembly needs.

Part Context

The ICL7631 belongs to the ICL761x-ICL764x series of CMOS operational amplifiers from Maxim Integrated. This series provides multiple amplifier configurations in various packages. The ICL7631 specifically integrates three amplifiers, offering a compact solution for multi-channel signal conditioning tasks compared to single-op-amp alternatives.

Replacement Considerations

The ICL7631ECPE+ is listed as a direct substitute. Verify pinout compatibility and electrical specifications match the original design requirements.
