Texas Instruments' ADS124S06 is a precision, 24-bit, delta-sigma (ΔΣ), ADC offering low power consumption and many integrated features to reduce system cost and component count in applications measuring small signal sensors.
This ADC features a configurable digital filter that offers low-latency conversion results and 50 Hz or 60 Hz rejection for noisy industrial environments. A low-noise, programmable gain amplifier (PGA) provides gains ranging from 1 to 128 to amplify low-level signals for resistive bridge or thermocouple applications. Additionally, these devices integrate a low-drift, 2.5 V reference that reduces printed circuit board (PCB) area. Finally, two programmable excitation current sources (IDACs) allow for easy and accurate RTD biasing.
An input multiplexer supports six inputs for the ADS124S06 that can be connected to the ADC in any combination for design flexibility. In addition, this device includes features such as sensor burn-out detection, voltage bias for thermocouples, system monitoring, and four general-purpose I/Os (GPIO).
