ICL7652BCPA

Overview

The ICL7652BCPA is a zero-drift operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a 16-SOIC package and operates within a supply voltage range of 5 V to 16 V. Key electrical parameters include an input offset voltage of 700 µV, a supply current of 2 mA, and an input bias current of 15 pA. The device offers a gain-bandwidth product of 450 kHz and a slew rate of 0.5 V/µs. It supports a commercial operating temperature range of 0°C to 70°C.

Feature Summary

• Zero-drift architecture utilizing chopper stabilization for continuous error correction
• Ultra-low input bias current suitable for high-impedance signal sources
• Rail-to-rail output capability with millivolt swing proximity to supply voltages

Applications

• Low-level signal processing applications requiring high precision
• Strain gauge and thermocouple amplification circuits
• Medical instrumentation and sensor interface designs

Procurement Notes

Verify the specific suffix 'BCPA' against official manufacturer documentation, as standard listings often reference 'CWE+'. Confirm RoHS compliance status and check for obsolescence notices, as this component family may have discontinued variants. Ensure the source document explicitly identifies the BC grade and PA package configuration before procurement.

Selection Notes

Select this component when ultra-low drift and low offset voltage are critical requirements. The zero-drift technology minimizes errors caused by temperature variations over time. Consider the 450 kHz bandwidth and 0.5 V/µs slew rate for application speed limitations. Verify that the 16-pin SOIC footprint matches the target PCB layout constraints.

Part Context

This part belongs to the ICL7652 series of chopper-stabilized operational amplifiers designed for precision analog signal conditioning. The series combines CMOS input stages with internal chopping mechanisms to achieve exceptional DC accuracy.
