The ADS1258IRTCR is a 16-channel (multiplexed) low-noise 24-bit delta-sigma () analog-to-digital converter (ADC) that provides single-cycle stable data at channel scan rates from 1.8k to 23.7k per channel per Samples per second (SPS). A flexible input multiplexer accepts a combination of 8 differential or 16 single-ended inputs with a full-scale differential range of 5V or a true bipolar range of ±2.5V when operating with a 5V reference. The fourth-order delta-sigma modulator is followed by a fifth-order sinc digital filter optimized for low noise performance.

The differential outputs of the multiplexer are accessible to allow signal conditioning prior to the ADC input. Internal system monitor registers provide supply voltage, temperature, reference voltage, gain and offset data.
