ICL7650SCPD

Overview

The ICL7650SCPD is a single-channel super chopper-stabilized operational amplifier manufactured by Renesas Electronics. It features a gain-bandwidth product of 2 MHz and a slew rate of 2.5 V/µs. The device guarantees a maximum input offset voltage of 8 µV and an input bias current of 10 pA. Operating from dual supply voltages ranging from 2.25 V to 8 V, it delivers a minimum output source/sink current of 30 mA. Key performance metrics include a common-mode rejection ratio (CMRR) of 140 dB and a power supply rejection ratio (PSRR) of 120 dB. The component is housed in a 14-pin DIP package.

Feature Summary

• Chopper-stabilized architecture ensures exceptionally low input offset voltage with minimal long-term and temperature drift.
• Integrated clamp circuit prevents overload recovery problems and enables comparator functionality.
• Extremely wide common-mode voltage range supports operation across diverse signal conditions.
• User-transparent CMOS design virtually eliminates traditional chopper amplifier issues such as intermodulation effects.

Applications

• Precision sensor signal conditioning
• High-impedance measurement circuits
• Low-drift instrumentation amplifiers

Procurement Notes

Verify the specific pinout configuration for the 14-pin DIP variant against the official datasheet, as package variations exist within the series. Confirm RoHS compliance status if required for your assembly process. Ensure the selected supplier provides traceable documentation matching the Renesas or Intersil manufacturer designation to avoid counterfeit components.

Selection Notes

Select this component when ultra-low offset voltage and drift are critical requirements. The chopper-stabilized technology offers superior DC accuracy compared to standard CMOS op-amps. Consider the 14-pin package availability versus the 8-pin variants if board space permits. Verify that the 2 MHz bandwidth meets the application's frequency response needs.

Part Context

This part belongs to the ICL7650 family of super chopper-stabilized amplifiers. It serves as an improved direct replacement for the industry-standard ICL7650, offering enhanced input offset voltage, lower temperature coefficient, and reduced input bias current. The series is designed for applications requiring high precision and stability over time and temperature.

Replacement Considerations

The ICL7650S is documented as a direct replacement for the industry-standard ICL7650. Verify pin compatibility before substituting other second-source parts. Check electrical specifications to ensure the substitute meets the required offset and bias current limits.
