CS5524-ASZ – CIRRUS

The CS5524-ASZ, manufactured by Cirrus Logic, is a high-resolution, multi-channel analog-to-digital converter (ADC) employing sigma-delta modulation. This integrated circuit features a 24-bit conversion resolution, enabling high-precision measurements in demanding applications. The device incorporates a fourth-order modulator followed by a digital filter, providing excellent noise performance and linearity. The CS5524-ASZ is specifically designed for applications requiring simultaneous sampling of multiple analog inputs, typically supporting up to four differential or eight single-ended channels. It operates from a single +5V analog supply and a +3V or +5V digital supply. The device communicates via a serial interface, typically SPI or Microwire, and is housed in a 24-pin Shrink Small Outline Package (SSOP), facilitating surface mount assembly. Internal calibration circuitry minimizes offset and gain errors, ensuring accuracy over temperature and time.
