General Description

The AD7738 is a high precision, high throughput analog front end.

True 16-bit p-p resolution is achievable with a total conversion time of 117 µs (8.5 kHz channel switching), making it ideally suitable for 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 a 15.4 kHz.
