AD-ADC-dat
AD7911/AD7921 - 2-Channel, 2.35 V to 5.25 V 250 kSPS, 10-/12-Bit ADCs
- AD7715 == 3 V/5 V, 450 µA 16-Bit, Sigma-Delta ADC
The AD7715 is a complete analog front end for low frequency measurement applications. The part can accept low level input signals directly from a transducer and outputs a serial digital word.
It employs a Σ-Δ conversion technique to realize up to 16 bits of no missing codes performance.
The 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 the on-chip control register allowing adjustment of the filter cutoff and output update rate.
