摘要：An analog front-end circuit for measurement used as an interface between asensor and a control device includes: an isolated part including at least an AD conversioncircuit configured to serve as an interface to the sensor; a non-isolated part including at
least a control circuit configured to serve as an interface to the control device; and anisolated communication unit configured to perform isolated half-duplex communicationbetween the isolated part and the non-isolated part. The control circuit is configured totransmit an AD conversion instruction to the AD conversion circuit after providing settingfor measurement to the isolated part via the isolated communication unit, obtain a resultof AD conversion by the AD conversion circuit from the isolated part via the isolatedcommunication unit, and transfer the obtained AD conversion result to the control device.
