CS3014-FSZ

Overview

The CS3014-FSZ is a dual precision operational amplifier manufactured by Cirrus Logic, housed in an 8-lead SOIC package. It operates on supply voltages from 2.7 V to 5 V with a typical supply current of 1.0 mA. Key electrical characteristics include a maximum input offset voltage of ±20 µV and a maximum average input offset drift of ±0.05 µV/°C. The device provides a typical open-loop voltage gain of 135 dB and exhibits low noise performance with a density of 22 nV/√Hz at 1 Hz and 1 kHz.

Feature Summary

• Features rail-to-rail inputs and outputs capable of swinging within 20 mV of the supply rails
• Designed for precision amplification of low-level signals with excellent offset stability
• Exhibits high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR)

Applications

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

Procurement Notes

Verify that the specific part number suffix matches the required package type and environmental compliance. The 'Z' suffix indicates lead-free construction. Confirm the operating temperature range requirements align with the -40 °C to +125 °C specification provided in the ordering information section of the datasheet.

Selection Notes

Select this component when low offset voltage and minimal drift are critical for signal integrity. The dual-channel architecture allows for cost-effective implementation in multi-sensor applications. Ensure the system supply voltage remains within the 2.7 V to 5 V range to maintain specified performance parameters.

Part Context
