Overview

The ADS124S08IPBSR is a high-precision, 24-bit delta-sigma analog-to-digital converter (ADC) featuring 12 analog input channels and an integrated low-noise programmable gain amplifier (PGA). It is designed to simplify the measurement of small signals from sensors like RTDs, thermocouples, and strain gauges by integrating a flexible multiplexer and internal fault detection circuits.

Why Choose This Part

This ADC integrates a variety of system-monitoring features including CRC-protected SPI communication, internal temperature sensing, and extended fault detection. The low-drift internal reference and 19 nV/rtHz noise floor allow for high-accuracy measurements without the need for extensive external signal conditioning.

Applications

Temperature Measurement
Ideal for RTD and thermocouple measurement systems requiring high resolution and integrated burnout detection.
Weight Scales and Strain Gauges
Utilizes the low-noise PGA and 24-bit resolution to capture minute voltage changes from bridge-based sensors.
Industrial Process Control
Suitable for 4-20mA loop monitoring and PLC analog input modules where high accuracy and low power consumption (250 uA typical) are required.
