AD7705BRZ 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. The selected input signal is applied to a proprietary, programmable-gain front end based around an analog modulator. The modulator output is processed by an on-chip digital filter. The first notch of this digital filter can be programmed via an on-chip control register, allowing adjustment of the filter cutoff and output update rate.
Features
- Two Fully Differential Input Channel ADCs
- Programmable Gain Front End Gains from 1 to 128
- Three-Wire Serial Interface
SPI®, QSPI™, MICROWIRE™ and DSP Compatible Schmitt Trigger Input on SCLK
