CS3004-FSZ

Overview

The CS3004-FSZ is a dual precision operational amplifier manufactured by Cirrus Logic. It features a maximum input offset voltage of ±10 µV and an average drift of ±0.05 µV/°C. The device provides a typical open-loop voltage gain of 150 dB and operates with a supply current of 2.1 mA. Input noise density is 17 nV/√Hz, while output swing reaches within 10 mV of the supply rails. It supports supply voltages from 2.7 V to 5 V and functions across a temperature range of -40 °C to +125 °C.

Feature Summary

Rail-to-rail input and output capabilities for extended dynamic range
Chopper-stabilized architecture ensuring low offset and drift
High common-mode rejection and power-supply rejection ratios

Applications

Thermocouple and thermopile signal amplification
Load cell and bridge transducer conditioning
Precision instrumentation circuits
Battery-powered measurement systems

Procurement Notes

Verify the specific suffix 'FSZ' indicates lead-free construction when sourcing replacements. Confirm that the thermal die pad connection requirements match the target PCB layout design. Ensure the operating environment remains within the specified -40 °C to +125 °C range for guaranteed performance parameters.

Selection Notes

Select this component for applications requiring high DC accuracy and low noise in single-supply environments. The rail-to-rail inputs allow full signal utilization near ground potential. Consider the 8-lead SOIC package dimensions for board space constraints compared to QFN alternatives.

Part Context

This part belongs to the CS3004 series of low-voltage precision amplifiers. It shares architectural similarities with the CS3012 and CS3014 models but offers distinct electrical characteristics tailored for general-purpose precision tasks. The series emphasizes stability and low power consumption for portable electronics.
