Working Principle

The AD7866BRUZ consists of a dual-slope integrator, a sigma-delta modulator and a decimation filter. The dual-slope integrator integrates the input signal and feeds it to the sigma-delta modulator which in turn converts it to a digital signal. The output of the sigma-delta modulator is then passed through the decimation filter which removes unwanted noise and improves the resolution of the output signal. The output of the filter is then converted to a digital value which can be directly read by a microcontroller.

The AD7866BRUZ is an advanced sigma-delta ADC that offers unparalleled performance for a variety of industrial applications. Its wide input range, high sampling rate and integrated decimation filter make it an ideal choice for applications requiring high accuracy and signal resolution. Additionally, the internal reference ensures that the converter is immune to power supply variations, making it suitable for use in harsh environments.
