CS5529-AP

Analog To Digital Converters (ADC) Overview

The CS5529-AP is a low-power, programmable 16-bit delta-sigma analog-to-digital converter (ADC) manufactured by Cirrus Logic. It integrates coarse and fine charge buffers, a fourth-order delta-sigma modulator, a calibration microcontroller, and a digital filter with selectable decimation rates. The device features an eight-filter configuration offering output word rates that settle in one conversion cycle, including simultaneous 50/60 Hz ±3 Hz rejection. It utilizes a simple three-wire serial interface compatible with SPI and Microwire standards and includes a 6-bit output latch for system flexibility.

Analog To Digital Converters (ADC) Part Context

The CS5529-AP belongs to the CS5529 family of 16-bit programmable ADCs from Cirrus Logic. This series is characterized by its integrated charge buffers and calibration logic, designed to simplify front-end circuitry. The 'AP' suffix typically denotes specific packaging or temperature grade variations within the standard CS5529 product line, sharing core electrical specifications with variants like the ASZR and ASZ.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the CS5529-ASZR and CS5529-ASZ. Designers should verify package dimensions and operating temperature ranges when substituting these variants, as they share identical functional descriptions but may differ in reel quantities or industrial grade certifications.
