CS5531-AS

Analog To Digital Converters (ADC) Overview

The CS5531-AS is a highly integrated delta-sigma analog-to-digital converter (ADC) manufactured by Cirrus Logic Inc. It utilizes charge-balance techniques to achieve 16-bit performance. The device features a chopper-stabilized programmable gain instrumentation amplifier (PGIA) with gains ranging from 1x to 64x, providing ultra-low noise characteristics of 12 nV/√Hz at 0.1 Hz. It includes a two-channel differential multiplexer and supports scalable input spans via calibration. The ADC offers selectable word rates from 6.25 to 3,840 Sps and includes R/W calibration registers per channel for precise measurement applications.

Analog To Digital Converters (ADC) Part Context

The CS5531-AS belongs to the CS5531/32/33/34 family of ADCs. While the CS5531 provides 16-bit resolution, sibling models in this series offer different bit depths and channel counts, such as the 24-bit CS5532. This family is designed for low-level signal measurement where high accuracy and low noise are critical requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers for the CS5531-AS are not available in the provided documentation. Users should verify compatibility with newer revisions or alternative families through official manufacturer channels.
