General Description

This device is a 7th order sigma-delta modulator that converts the analog input signal into a high speed 1-bit data stream.

The part operates from a +5 V supply and accepts a differential input range of 0 V to +2.5 V or ± 1.25 V centered about a commonmode bias.

The analog input is continuously sampled by the analog modulator, eliminating the need for external sample and hold circuitry.
