Isolated high voltage sensor

00:11:25

A high-voltage voltage divider with a buffer stage followed by a unity-gain difference amplifier; the sensor is in a floating state due to having a different reference from the high-voltage circuit. An isolated power supply is required to power the Op Amps and the sensor. The idea is to keep a current of 2.5mA in a 2k resistance
