AD7707 Datasheet (Analog Devices)

AD7707, Sigma-Delta ADC

The AD7707 is a complete analog front end for low frequency measurement applications.

This 3-channel device can accept either low level input signals directly from a transducer or high level (±10 V) signals and produce a serial digital output.

It employs a Σ-Δ conversion technique to realize up to 1
