AD7790 General Description

The AD7790 is a low power, complete analog front end for low frequency measurement applications. It contains a low noise 16-bit ∑-Δ ADC with one differential input that can be buffered or unbuffered along with a digital PGA, which allows gains of 1, 2, 4, and 8. The device operates from an internal .
