AD7705 - Sigma-Delta ADCs

Download the AD7705 datasheet PDF. This datasheet also covers the AD7706 variant, as both devices belong to the same sigma-delta adcs family and are provided as variant models within a single manufacturer datasheet.

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.

Features

  • AD7705: 2 fully differential input channel ADCs AD7706: 3 pseudo differential input channel ADCs 16 bits no missing codes 0.003% nonlinearity Programmable gain front end: gains from 1 to 128 3-wire serial interface SPI®-, QSPI™-,.
