24-bit 128Ksps Analog front end (AFE) having sigma delta ADC for Energy Metering application

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 128 Ksps . The digital filter can be programmed for a fast settling mode where the conversions settle in a single cycle, or programmed.
