ICL7612BCPA

Overview

The ICL7612BCPA is a single-channel, low-power operational amplifier manufactured by Intersil. It features a chopper-stabilized architecture designed to minimize offset voltage and drift. The device operates within a supply voltage range of 1V to 8V per rail or 2V to 16V total. Key electrical parameters include a gain-bandwidth product of 1.4 MHz, a slew rate of 1.6 V/us, an input bias current of 50 pA, and an input offset voltage of 15 mV. It is housed in an 8-pin PDIP package.

Feature Summary

• Chopper-stabilized design for low offset voltage and drift
• Low power consumption suitable for battery applications
• Single channel configuration with general-purpose performance

Applications

• Precision sensor signal conditioning
• Low-level DC amplification
• Instrumentation front-ends

Procurement Notes

Verify the manufacturer origin as Intersil or its successor Renesas Electronics. Confirm the package type is PDIP-8 and the temperature grade matches commercial specifications. Ensure the part number suffix corresponds to the specific variant required for your circuit design.

Selection Notes

Select this component when low offset voltage and stability are critical but high speed is not required. Compare against other chopper amplifiers if lower noise or higher bandwidth is needed. Verify that the 1.4 MHz bandwidth meets the application's frequency response requirements.

Part Context

This part belongs to the ICL7612 series of precision operational amplifiers. It shares architectural similarities with other chopper-stabilized op-amps from Intersil, offering improved DC accuracy over standard bipolar or CMOS amplifiers without the complexity of external trimming circuits.

Replacement Considerations

Check for direct replacements such as the ICL7612DCBAZ or ICL7612SCPA. Verify pin compatibility and electrical parameter equivalence before substitution.
