CS5566-ISZR

Analog To Digital Converters (ADC) Overview

The CS5566-ISZR is a single-channel, 24-bit analog-to-digital converter (ADC) manufactured by Cirrus Logic. It operates at a conversion rate of 5 kSps using delta-sigma architecture. The device features fully differential analog inputs with on-chip buffers for high input impedance. Power supply configurations include +5V/GND or ±2.5V for analog sections and +1.8V to +3.3V for I/O. Key electrical parameters include a linearity error of 0.0005%, signal-to-noise ratio of 110 dB, and power consumption of 20 mW at 5 kSps. It utilizes a simple three/four-wire serial interface.
