3 V/5 V, 1 mW 2-/3-Channel 16-Bit, Sigma-Delta ADCs

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
