AD7711 - Signal Conditioning ADC

Description

The AD7711 is a complete analog front end for low frequency measurement applications.

The device accepts low level signals directly from a transducer and outputs a serial digital word.

It employs a ⌺-⌬ conversion technique to realize up to 24 bits of no missing codes performance.
