The AD7738 is a high precision, high throughput analog frontend. True 16-bit p-p resoluTIon is achievable with a total conversionTIme of 117 μs (8.5 kHz channel switching), making itideally suitable for high resoluTIon mulTIplexing applications.The part can be configured via a simple digital interface, whichallows users to balance the noise performance against datathroughput up to a 15.4 kHz.The analog front end features eight single-ended or four fullydifferential input channels with unipolar or bipolar 625 mV,1.25 V, and 2.5 V input ranges and accepts a common-modeinput voltage from 200 mV above AGND to AVDD – 300 mV.The multiplexer output is pinned out externally, allowing theuser to implement programmable gain or signal conditioningbefore applying the input to the ADC.
