AD7703 Datasheet 20-Bit A/D Converter

Manufacturer: Analog Devices

Overview: LC2MOS 20-Bit A/D Converter AD7703.

General Description

The AD7703 is a 20-bit ADC that uses a S-D conversion technique.

The analog input is continuously sampled by an analog modulator whose mean output duty cycle is proportional to the input signal.

The modulator output is processed by an on-chip digital filter with a six-pole Gaussian response, which updates the output data register with 16-bit binary words at word rates up to 4 kHz.
