ICL7631ECJE

Overview

The ICL7631ECJE is a triple CMOS operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features rail-to-rail output capability and operates within a supply voltage range of 2 V to 16 V. The device provides three independent circuits in a 16-pin Ceramic Dual In-Line Package (CERDIP). Key electrical characteristics include a gain-bandwidth product of 1.4 MHz, a slew rate of 1.6 V/µs, and an input bias current of 1 pA. It supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Triple-channel CMOS architecture with rail-to-rail output swing
• Low input bias current for high-impedance signal applications
• Single-supply operation compatible with low-voltage systems

Applications

• Motor control DSP controller interfaces
• Real-time system stability monitoring
• General-purpose analog signal conditioning

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm the specific suffix 'JE' corresponds to the ceramic package variant required for your design. Check for lead-free compliance status if RoHS regulations apply to your manufacturing process. Ensure availability aligns with production timelines as legacy components may have limited stock.

Selection Notes

Select this component when triple-channel amplification with rail-to-rail output is required in a robust ceramic package. It is suitable for designs needing low power consumption and single-supply operation. Compare against plastic DIP variants if cost or standard packaging is preferred over the higher thermal stability of CERDIP.

Part Context

This part belongs to the ICL7631 series of single, dual, triple, and quad operational amplifiers. It represents the triple-channel configuration housed in a 16-pin CERDIP package. The series is known for CMOS performance characteristics including low power and wide supply voltage ranges.

Replacement Considerations

ICL7631ECPE+ is listed as a direct substitute. Verify pinout compatibility and package dimensions between CERDIP and PDIP variants before substitution.
