AD7703 Datasheet (Analog Devices) - 20-Bit A/D Converter

AD7703, 20-Bit A/D Converter

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 u
