Analog To Digital Converters (ADC) datasheet and documents for CS5508-BSZ

CS5508-BSZ

Analog To Digital Converters (ADC) Overview

The CS5508-BSZ is a single-channel, 20-bit analog-to-digital converter (ADC) from Cirrus Logic. It utilizes delta-sigma architecture with an internal digital filter and supports output update rates up to 100 Sps. The device operates on dual supplies of ±5V or a single +5V supply, consuming as little as 1.7 mW. It features differential inputs, pin-selectable unipolar/bipolar ranges, and a flexible serial interface compatible with 3.3V or 5V logic levels. Linearity error is specified at ±0.0007% FS for the -B grade.

Analog To Digital Converters (ADC) Feature Summary

20-bit resolution with linearity error of ±0.0007% FS (-B grade)
Single-channel differential input with pin-selectable unipolar/bipolar modes
Very low power consumption: 1.7 mW (+5V single supply), 3.2 mW (±5V dual supply)
On-chip self-calibration circuitry for offset and gain accuracy

Analog To Digital Converters (ADC) Applications

Measurement of low-frequency physical, chemical, and biological signals
Industrial process control systems requiring high precision
Weigh scales and load cell interfaces
Thermocouple and RTD temperature measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify component status as distribution sources indicate this part may be obsolete or end-of-life. Confirm specific ordering suffixes against manufacturer documentation to ensure correct package and temperature range specifications before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5508-BSZ for applications requiring single-channel, high-resolution DC signal acquisition. Ensure the design accommodates the required analog supply voltages (±5V or +5V) and reference voltage constraints (1.0V to 3.6V). Verify that the serial interface timing meets microcontroller requirements for SSC or SEC modes.

Analog To Digital Converters (ADC) Part Context

The CS5508 is part of the CS5505/6/7/8 family of very low power A/D converters. While the CS5505 and CS5506 offer four pseudo-differential channels, the CS5507 and CS5508 provide single-channel configurations. The CS5508 specifically delivers 20-bit resolution compared to the 16-bit resolution of the CS5507.
