ICL7612ACSA

Overview

The ICL7612ACSA+ is a single-channel CMOS operational amplifier from the ICL761X family, housed in an 8-SOIC surface-mount package. It operates on supply voltages ranging from ±1V to ±8V or single supplies of 2V to 16V. Key electrical parameters include a gain-bandwidth product of 44 kHz, a slew rate of 16 mV/µs, and an input bias current of 50 pA. The device features a maximum input offset voltage of 3 mV and a quiescent current of 15 µA. It supports rail-to-rail output swing and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Ultra-low input bias current suitable for high-impedance signal sources
• Rail-to-rail output capability allowing full dynamic range utilization
• Pin-selectable quiescent current options for power optimization

Applications

• Long time constant integrators
• High-impedance sensor interfaces
• Low-power data acquisition systems

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and specific suffix designations against official datasheets. Check lifecycle status as availability may be limited due to obsolescence. Ensure packaging integrity matches specified surface-mount requirements.

Selection Notes

Select this component for applications requiring low power consumption and high input impedance. Compare performance metrics such as slew rate and bandwidth against alternative CMOS op-amps. Consider thermal management within the specified operating temperature range. Evaluate pin compatibility if replacing legacy DIP variants with SOIC packages.

Part Context

Part of the ICL761X monolithic CMOS operational amplifier family designed for ultra-low input current and wide supply voltage operation. Manufactured by Analog Devices Inc./Maxim Integrated, these amplifiers combine low-power operation with precision characteristics suitable for battery-powered and portable electronic designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same CMOS family. Verify that substitute components meet the required 44 kHz bandwidth and 16 mV/µs slew rate specifications. Ensure equivalent input bias current levels are maintained for circuit stability.
