CS5501-BSZ

ADCs/DACs - Special Purpose Overview

The CS5501-BSZ is a low-cost, monolithic CMOS analog-to-digital converter (ADC) from Cirrus Logic. It utilizes charge-balance techniques to achieve 16-bit resolution with up to 4 kHz output word rates. The device features a 6-pole, low-pass Gaussian filter and on-chip self-calibration circuitry. Key performance metrics include a linearity error of ±0.0003% and differential nonlinearity of ±1/8 LSB, ensuring no missing codes. It operates with flexible serial communications compatible with microcontrollers and supports pin-selectable unipolar or bipolar input ranges.
