The AD7711A is a complete analog front end for low frequency
measurement applications. The device accepts low level signals
directly from a transducer and outputs a serial digital word. It
employs a sigma-delta conversion technique to realize up to
24 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 settling time.
