24-bit 19.2Ksps Analog front end (AFE) having sigma delta ADC for Industrial process control and low power sensors

Overview

The 24b ADC IP has a fourth-order, inherently stable, delta-sigma (??) modulator that provides good noise and linearity performance designed for the needs of industrial process control, precision instrumentation, and similar applications. The ADC has wide dynamic range, with scalable data rates up to 19.2Ksps. The digital filter can be programmed for a fast-settling mode where the conversions settle in a single cycle, or programmed
