Description
.
The AD7705/AD7706 are complete analog front ends for low frequency measurement applications.
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™-, MICROWIRE™-, and DSP-compatible
Schmitt-trigger input on SCLK Ability
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. The selected input signal is applied to a proprietary, programmable-gai
