General Description

The AD7721 is a complete low power, 12-/16-bit, sigma-delta ADC.

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

The analog input is continuously sampled by an analog modulator at twice the clock frequency eliminating the need for external sample-andhold circuitry.
