CS43L42-KZZR

Digital To Analog Converters Overview

The CS43L42-KZZR is a stereo digital-to-analog converter (DAC) manufactured by Cirrus Logic. It integrates interpolation, 1-bit D/A conversion, analog filtering, volume control, line-level outputs, and a headphone amplifier within a single package. The device supports 24-bit resolution and operates at sample rates up to 96 kHz. It functions with supply voltages ranging from 1.8 V to 3.3 V. Key performance metrics include a dynamic range of 96 dB at a 3 V supply and a total harmonic distortion plus noise (THD+N) of -85 dB. The component utilizes a 24-pin TSSOP package.
