CS3014-INZ

Overview

The CS3014-INZ is a general-purpose dual operational amplifier manufactured by Cirrus Logic Inc. It features a chopper-stabilized architecture designed for precision amplification of low-level signals, achieving excellent offset stability and high open-loop gain. The device operates with supply voltages ranging from 2.7 V to 5 V (±1.35 V to ±2.50 V). Key electrical characteristics include a maximum input offset voltage of 20 µV, a typical offset drift of 0.05 µV/°C, and a nominal common-mode rejection ratio of 120 dB. It utilizes an 8-pin SOIC package.

Feature Summary

• Chopper-stabilized architecture ensures excellent offset stability and low noise performance.
• Rail-to-rail output capability allows the common mode input range to include the supply rails.
• Designed for precision amplification of low-level signals with high open-loop gain.

Applications

• Precision signal conditioning
• Low-level sensor interface circuits
• Battery-powered instrumentation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing lot codes if required for traceability. Review the latest datasheet for any potential product change notices or obsolescence warnings prior to final procurement decisions.

Selection Notes

Select this component when high DC accuracy and low drift are critical requirements. The chopper-stabilized design minimizes offset voltage errors compared to standard op-amps. Ensure the application supply voltage falls within the specified 2.7 V to 5 V range and that the 8-pin SOIC package fits the PCB layout constraints.

Part Context

The CS3014 belongs to the CS3004 series of low-power, low-voltage precision amplifiers. This family is engineered for applications demanding high precision in small form factors. The INZ suffix typically indicates a lead-free and RoHS-compliant variant of the standard CS3014 part number.
