CS5532-BSZR

Analog To Digital Converters (ADC) Overview

The CS5532-BSZR is a 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Cirrus Logic Inc. It features a chopper-stabilized programmable gain instrumentation amplifier (PGIA) with gains ranging from 1x to 64x, achieving an input noise density of 12 nV/√Hz at 0.1 Hz. The device supports two differential inputs and offers selectable output data rates from 6.25 Sps to 3,840 Sps. It utilizes a three-wire serial interface compatible with SPI and Microwire standards. The component is housed in a 20-pin SSOP package and operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Part Context

The CS5532-BSZR belongs to the CS553x family of high-performance ADCs, which also includes the CS5531 (16-bit), CS5533 (16-bit), and CS5534 (24-bit). The suffix 'B' typically denotes a specific temperature or performance grade, while 'Z' indicates RoHS compliance. The 'R' suffix specifies tape-and-reel packaging for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the CS5532-ASZR (different temperature/package grade) or the CS5534-BSZR if four channels are required. Cross-family alternatives like the CS5530 series offer similar interfaces but may differ in channel count or specific noise characteristics.
