CS53L32A-KZ

Analog To Digital Converters (ADC) Overview

The CS53L32A-KZ is a highly integrated, low-voltage stereo audio analog-to-digital converter (ADC) manufactured by Cirrus Logic. It utilizes delta-sigma conversion techniques to provide 24-bit resolution and supports sample rates up to 96 kHz. The device operates on a single supply voltage ranging from 1.8 V to 3.3 V, with power consumption as low as 11 mW at 1.8 V. Key electrical specifications include a dynamic range of 98 dB at a 3 V supply and a total harmonic distortion plus noise (THD+N) of -88 dBFS. The component is housed in a compact 20-pin TSSOP package.
