AD7706 Datasheet Sigma-Delta ADCs

Manufacturer: Analog Devices

General Description

The AD7705/AD7706 are complete analog front ends for low frequency measurement applications.

These 2-/3-channel devices can accept low level input signals directly from a transducer and produce serial digital output.

The devices employ a Σ-Δ conversion technique to realize up to 16 bits of no missing codes performance.
