CS5381-KZZR

Analog To Digital Converters (ADC) Overview

The CS5381-KZZR is a 24-bit stereo audio analog-to-digital converter utilizing an advanced multi-bit delta-sigma architecture. It integrates sampling, anti-alias filtering, and conversion to generate serial PCM data at sample rates up to 216 kHz per channel. The device features a differential analog input structure for superior noise rejection and includes internal digital filters that eliminate the need for external anti-alias components. Key electrical specifications include a dynamic range of 120 dB (A-weighted) and total harmonic distortion plus noise of -110 dB. It operates with an analog supply of 5 V and digital/logic supplies ranging from 2.5 V to 5 V, consuming approximately 260 mW in normal operation.
