The AD7400/AD7401 are 2nd order sigma-delta modulators

that convert an analog input signal into a high speed 1-bit data

stream with onboard digital isolation based on Analog Devices’

iCoupler® technology. The AD7400/AD7401 operate from a 5 V

power supply and accept a differential input signal of 200 mV.

The analog input is continuously sampled by the analog

modulator, eliminating the need for external sample and hold

circuitry. The input information is contained in the output

stream as a density of ones with data rates up to 20MHz. The

original information can be reconstructed with an appropriate

digital filter. The serial I/O may use a 5V or 3V supply (V_DD2).
