Abstract
A detection device includes: a sensor circuit; an AFE circuit configured to acquire a detection signal from the sensor circuit; a control circuit configured to control the AFE circuit; a reference potential generation circuit configured to operate with a first reference potential as a ground potential and generate a second reference potential synchronized with a square wave signal output from the AFE circuit; a first isolator provided on a transmission path for the square wave signal between the AFE circuit and the reference potential generation circuit; and a second isolator provided on a signal transmission path between an external processing device that operates with the first reference potential as the ground potential and the control circuit. The AFE circuit and the control circuit operate with the second reference potential as the ground potential, and signal transmission paths between the AFE circuit and the control circuit are electrically coupled.
