Isolated Data Acquisition System Circuit composed by AD7714 and Microprocessor
The above picture is a isolating data acquisition made up of five-channel low-dissipation programmable sensor signal processor AD7714 and micro-processor. AD7714 is available in low-dissipation narrow-bandwidth, and high-resolution data acquisition system. Three-line serial interface enables the data acquisition system to realize isolating by only three optical couplers. If input signals from AD7714 analog input end are positive, then the whole system canuse a single-power-supply of +3V or +5V.
