Analog Devices AD7701ARZ AD7701ARZ ADC 16BIT 4KSPS WSOIC-20
AD7701 is a 16bit ADC that uses a sigma-delta conversion technique. The analogue input is continuously sampled by an analogue 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 16bit binary words at w word rates up to 4KHz. The sampling rate, filter corner frequency and output word rate are set by a clock input that may be supplied externally or by a crystal controlled on-chip clock oscillator. The inherent 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. Typical application include industrial process control, weigh scales, portable instrumentation, remote data acquisition.
