Datasheet:: AD7731BRU

Overview

Description
The AD7731 is a 24-bit sigma-delta analog-to-digital converter (ADC) designed for process control applications. It features a programmable gain front end that allows it to accept a wide range of input signal ranges, including low-level signals directly from transducers. The sigma-delta architecture consists of an analog modulator and a low-pass programmable digital filter, enabling adjustment of filter cutoff, output rate, and settling time.

Features
24-bit resolution
16-bit peak-to-peak resolution at 800 Hz output rate
Programmable output rates up to 6.4 kHz
Programmable gain front end
±0.0015% nonlinearity
Buffered differential inputs
Programmable filter cutoffs
FASTStep™ mode for channel sequencing
Single supply operation

Applications
Process control
PLCs/DCS
Industrial instrumentation
Low noise, high throughput 24-bit sigma-delta ADC
