ICL7631BCPE+

Overview

The ICL7631BCPE+ is a triple CMOS operational amplifier from the ICL761X–ICL764X family, housed in a 16-lead Plastic Dip package. It operates within a supply voltage range of ±1V to ±8V or single supplies from 2V to 16V. Key electrical characteristics include a unity-gain bandwidth of 0.044 MHz, an input bias current of 50 pA (max), and an input offset voltage of 10 mV (max). The device features pin-selectable quiescent currents of 10µA, 100µA, or 1000µA per amplifier.

Feature Summary

• Monolithic low-power CMOS design with ultra-low input bias current
• Pin-selectable quiescent current settings for power-bandwidth optimization
• CMOS outputs capable of swinging to within millivolts of supply rails

Applications

• Long-time constant integrators
• Picoammeters
• Low-leakage amplifiers
• Low-frequency active filters

Procurement Notes

Verify the component datasheet against the manufacturer's official documentation to confirm the specific B grade offset voltage and temperature range specifications. Ensure the ordering suffix matches the required lead-free status and packaging format. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when applications require extremely low input bias currents and high input impedance. The triple configuration allows for multiple signal paths in a single package. Consider the programmable quiescent current feature to balance power consumption against bandwidth and slew rate requirements for the specific circuit topology.

Part Context

This part belongs to the ICL761X–ICL764X series of monolithic CMOS operational amplifiers. The 'B' designation indicates a maximum input offset voltage of 10mV, while the 'C' denotes a commercial temperature range of 0°C to +70°C. The 'PE' suffix specifies the 16-lead plastic DIP package format.

Replacement Considerations

Check for other members of the ICL763X family, such as the ICL7631ACPE or ICL7631DCPE, which offer different offset voltage grades and temperature ranges. Verify that any substitute maintains the same triple amplifier configuration and 16-pin PDIP footprint.
