ADS1258 General Description

The ADS1258 is a 16-channel (multiplexed), low-noise, 24-bit, delta-sigma (DS) analog-to-digital converter (ADC) that provides single-cycle settleddata at channel scan rates from 1.8k to 23.7k samples per second (SPS). A flexible input multiplexer accepts combinations of eight differential or 16 single-ended inputs with a full-scale differential range of 5V or 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 output of the multiplexer is accessible to allow signal conditioning prior to the input of the ADC. Internal system monitor registers provide supply voltage, temperature, reference voltage, gain, and offset data.

An onboard PLL generates the system clock from a 32.768kHz crystal, or can be overridden by an external clock source. A buffered system clock output(15.7MHz) is provided to drive a microcontroller or additional converters.
