16-Bit Sigma-Delta ADC

The AD7701 is a 16-bit ADC which uses a sigma delta conversion technique. The Analog input is continually 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 tha output data Register with 16-bit binary words at word rates up to 4kHz. The sampling rate, Filter corner frequency and output word rate are set by a master Clock input that may be supplied externally, or by a crystal-controlled on-chip Clock Oscillator
The inherant linearity of the ADC is excellent, and endpoint accuracy is ensured by self-calibration of zero and full scale which may be initiated at any time. The self-calibration scheme CAN also be extended to null system offset and gain errors in the input channel.
The output data is accessed through a flexible serial port, which has an asynchronous mode compatible with UARTs and two synchronous modes suitable for interfacing to Shift registers or the serial ports of industry-standard Microcontrollers
CMOS construction insures low power dissipation, and a power down mode reduces the idle power consumption to only 10 W.
