Texas Instruments ADS114S06IRHBT

The ADS114S06 and ADS114S08 are precision,16-bit, delta-sigma (ΔΣ),analog-to-digital converters (ADCs) that offer low power consumption and many integrated featuresto reduce system cost and component count in applications measuring small-signal sensors.

These ADCs feature configurable digital filters that offer low-latency conversion resultsand 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 orthermocouple applications. Additionally, these devices integrate a low-drift, 2.5-V reference thatreduces printed circuit board (PCB) area. Finally, two programmable excitation current sources(IDACs) allow for easy and accurate RTD biasing.

An input multiplexer supports 12 inputs for the ADS114S08 and sixinputs for the ADS114S06 that can be connected to the ADC in any combination fordesign flexibility. In addition, these devices include features such as sensor burn-out detection,voltage bias for thermocouples, system monitoring, and four general-purpose I/Os.

The devices are offered in a leadless VQFN-32 or a TQFP-32 package.
