ICL7622BCSD

Overview

The ICL7622BCSD is a single-channel, chopper-stabilized operational amplifier manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes CMOS technology and features a SOIC-14 surface-mount package. Key electrical specifications include a gain-bandwidth product of 2 MHz, a slew rate of 2.5 V/us, an input offset voltage of 10 uV, and an input bias current of 20 pA. The device operates on supply voltages ranging from 2.25 V to 8 V (dual) or 4.5 V to 16 V (single), with a typical operating current of 3.5 mA. It offers a common-mode rejection ratio of 120 dB and power supply rejection of 120 dB, functioning within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Chopper stabilization architecture for ultra-low input offset voltage and drift
• CMOS construction enabling low quiescent current consumption
• Rail-to-rail output capability swinging close to supply rails
• High common-mode and power supply rejection ratios

Applications

• Precision signal conditioning in instrumentation systems
• Low-drift integrator circuits requiring long time constants
• Picoammeter front-end amplification stages
• Sample-and-hold amplifier applications demanding low droop rates

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm that the specific suffix matches the required package and temperature grade. Review the official datasheet for any recent design-in notices or lifecycle status updates prior to final procurement decisions.

Selection Notes

Select this component when ultra-low offset voltage and minimal drift are critical requirements over standard precision op-amps. Ensure the application benefits from chopper stabilization without sensitivity to switching noise artifacts. Verify that the 2 MHz bandwidth and 2.5 V/us slew rate meet the dynamic performance needs of the target circuit design.

Part Context

This part belongs to the ICL7650B series of high-performance, chopper-stabilized operational amplifiers. It shares architectural similarities with other members of the family but is configured as a single-channel device in a 14-pin SOIC package. The series is designed for applications requiring DC precision and stability without the need for external trimming.

Replacement Considerations

Consult official substitution guides for verified equivalents. Generic replacements may not match the specific chopper-stabilized characteristics or pinout configuration.
