Datasheet
AD7739 is an 8-channel, high throughput, 24-bit ∑-∆ ADC with features such as high resolution, optimized fast channel switching, configurable inputs, and on-chip per channel system calibration. It is suitable for applications such as PLCs/DCSs, multiplexing, process control, and industrial instrumentation.
Datasheet
The AD7739 is a high precision, high throughput analog front end. True 16-bit p-p resolution is achievable with a total conversion time of 250 μs (4 kHz channel switching), making it ideally suited to high resolution multiplexing applications. The part can be configured via a simple digital interface, which allows users to balance the noise performance against data throughput up to 15 kHz. The analog front end features eight single-ended or four fully differential input channels with unipolar or bipolar 625 mV, 1.25 V, and 2.5 V input ranges. It accepts a common-mode input voltage from 200 mV above AGND to AVDD – 300 mV. The differential reference input features “No-Reference” detect capability. The ADC also supports per channel system calibration options.
