CS3003-FS

Overview

The CS3003-FS is a dual operational amplifier manufactured by Cirrus Logic Inc., designed for precision signal amplification. It features a chopper-stabilized architecture to achieve low offset voltage and minimal drift, ensuring high accuracy for low-level signals. The device operates on a single supply voltage ranging from 2.7 V to 5 V. Key electrical characteristics include a maximum input offset voltage of 20 µV and a typical bias current of 0.001 µA at 25°C. It offers a nominal common-mode rejection ratio of 120 dB and includes internal frequency compensation.

Feature Summary

• Chopper-stabilized architecture for excellent offset stability and low noise
• Low power consumption suitable for portable applications
• High open-loop gain and common-mode rejection ratio
• Input common-mode range extends to the supply rails

Applications

• Precision amplification of low-level sensor signals
• Battery-powered instrumentation systems
• Medical equipment requiring low drift performance
• Data acquisition front-ends

Procurement Notes

Verify the exact suffix 'FS' against official datasheets to confirm package type and temperature grade. Confirm availability status as some Cirrus Logic components may be discontinued or subject to last-time buy notices. Ensure compatibility with required supply voltage ranges and operating temperature specifications before procurement.

Selection Notes

Select this component when low offset voltage and drift are critical requirements. The chopper-stabilized design makes it suitable for DC-coupled applications where long-term stability is needed. Compare performance metrics such as input bias current and CMRR against other precision op-amps in the portfolio to ensure fit for specific signal conditioning tasks.

Part Context

The CS3003 belongs to the CS3004 family of dual precision amplifiers from Cirrus Logic. These devices are engineered for applications demanding high accuracy and stability. The family shares similar architectural features, including chopper stabilization and rail-to-rail input capabilities, tailored for low-voltage, low-power environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the Cirrus Logic portfolio. Verify that any substitute maintains the same chopper-stabilized performance and supply voltage range. Consult manufacturer documentation for end-of-life notifications regarding the CS3003 series.
