AD7715 Datasheet (Analog Devices)

AD7715, Sigma-Delta ADC

The AD7715 is a complete analog front end for low frequency measurement applications.

The part can accept low level input signals directly from a transducer and outputs a serial digital word.

It employs a Σ-Δ conversion technique to realize up to 16 bits of no missing codes performance.
