Low-power delta-sigma ADC With PGA ideally suited for applications measuring small sensor signals

The Texas Instruments ADS112U04 is a precision, 16-bit, ADC offering many integrated features to reduce system cost and component count in applications measuring small sensor signals. The device features two differential or four single-ended inputs through a flexible input multiplexer, a low-noise, PGA, two programmable excitation current sources, an oscillator, a voltage reference, and a precision temperature sensor. The device can perform conversions at data rates up to 2000 SPS with single-cycle settling. At 20 SPS, the digital filter offers simultaneous 50Hz and 60Hz rejection for noisy industrial applications. The internal PGA provides gains up to 128. This PGA makes the device suited for applications measuring small sensor signals, such as RTDs, thermistors, thermocouples, and resistive bridge sensors. The device is offered in a leadless 16-pin WQFN or a 16-pin TSSOP package and is specified over a temperature range of –40C to +125C.
