应用功能:3 V/5 V, 1 mW2-/3-Channel 16-Bit, Sigma-Delta ADCs The AD7705/AD7706 are complete analog front ends for lowfrequency measurement applications. These two-/three-channeldevices can accept low level input signals directly from a transducerand produce a serial digital output. They employ a sigmadeltaconversion technique to realize up to 16 bits of no missingcodes performance.
