CS5381K-KSZ

Analog To Digital Converters (ADC) Overview

The CS5381K-KSZ is a 24-bit stereo audio analog-to-digital converter (ADC) from Cirrus Logic, housed in a 24-pin SOIC package. It utilizes an advanced multi-bit delta-sigma architecture to achieve a dynamic range of 120 dB and -110 dB THD+N. The device supports output sample rates up to 216 kHz per channel with differential analog inputs. Key electrical specifications include a 5 V analog supply, 3.3 V to 5 V digital/logic supplies, and 260 mW power consumption. It features internal voltage references, low-latency digital filtering, and overflow detection.
