CS3004-FSZR

Overview

The CS3004-FSZR is a dual precision operational amplifier manufactured by Cirrus Logic. It features rail-to-rail input and output capabilities, operating within a supply voltage range of 2.7 V to 5 V. Key electrical specifications include a maximum input offset voltage of ±10 µV, an average drift of ±0.05 µV/°C, and a typical open-loop gain of 150 dB. The device draws 2.1 mA of supply current and offers a slew rate of 0.25 V/µs. It is housed in an 8-lead SOIC package.

Feature Summary

• Rail-to-rail input and output swing capability
• Low input offset voltage and drift for high precision
• High common-mode rejection and power-supply rejection ratios

Applications

• Thermocouple and thermopile amplifiers
• Load cell and bridge transducer amplifiers
• Precision instrumentation circuits
• Battery-powered systems

Procurement Notes

Verify the specific suffix 'FSZR' against official documentation, as standard listings typically reference 'FSZ'. Confirm availability status, as this component may be subject to discontinuation or limited stock. Ensure the ordering information matches the required temperature range and package type before finalizing procurement.

Selection Notes

Select this component for applications requiring low noise and high precision with single-supply operation. The rail-to-rail performance allows for maximum dynamic range in low-voltage environments. Consider the 2.1 mA supply current when designing for battery-powered constraints.

Part Context

The CS3004 belongs to Cirrus Logic's family of precision low-voltage amplifiers. It is designed for signal conditioning tasks where accuracy is critical. The dual configuration provides two independent channels in a compact footprint, suitable for space-constrained designs.

Replacement Considerations

Check for direct pin-compatible alternatives if the CS3004-FSZR is unavailable. Verify that any substitute maintains the same rail-to-rail characteristics and precision parameters.
