CS5501-BSR

ADCs/DACs - Special Purpose Overview

The CS5501-BSR is a low-cost CMOS analog-to-digital converter manufactured by Cirrus Logic. It provides 16-bit resolution using charge-balance techniques, suitable for measuring low-frequency physical, chemical, and biological signals. The device integrates a 6-pole low-pass Gaussian filter to prevent aliasing and supports output word rates up to 4 kHz. Key electrical characteristics include a linearity error of ±0.0003% and differential nonlinearity of ±1/8 LSB with no missing codes. It features on-chip self-calibration, flexible serial communication interfaces compatible with microcontrollers, and pin-selectable unipolar or bipolar input ranges.
