AD7790 - 16-Bit Buffered Sigma-Delta ADC
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
