General Description

The ADS1258 is a 16-channel (multiplexed), low-noise, 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) that provides single-cycle settled data at channel scan rates from 1.8k to 23.7k samples per second (SPS) per channel.

A flexible input multiplexer accepts combinations of eight differential or 16 single-ended inputs with a full-scale differential range of 5 V or true bipolar range of ±2.5 V when operating with a 5-V reference.

The fourth-order delta-sigma modulator is followed by a fifth-order sinc digital filter optimized for low
