Cirrus Logic Inc. CS5534-BSZ

Description
The CS5532/34 are 24-bit analog-to-digital converters (ADCs) designed for measuring low-level unipolar or bipolar signals in various applications, including weigh scales, process control, scientific research, and medical devices. They feature a chopper-stabilized instrumentation amplifier with selectable gains from 1x to 64x, providing high dynamic range and low noise (6 nV/√Hz @ 0.1 Hz). The ADCs also include a fourth-order delta-sigma modulator and digital filter, offering programmable output word rates from 6.25 to 3,840 Sps.

Features
24-bit resolution with linearity error of 0.0007% FS
Noise-free resolution up to 23 bits
Two- or four-channel differential multiplexer
Scalable input span via calibration (±5 mV to differential ±2.5 V)
Scalable VREF input up to analog supply
Simple three-wire serial interface (SPI and Microwire compatible)
Schmitt trigger on serial clock (SCLK)
Selectable word rates (6.25 to 3,840 Sps)
Selectable 50 or 60 Hz rejection
