動装置。 In a driving device for a display meter that displays a physical quantity, there is a physical quantity detection section that detects the physical quantity as a digital signal and outputs the physical quantity signal, a conversion section that converts the physical quantity signal from an analog signal to a digital signal, and a digital signal output from the conversion section. A digital signal conversion processing unit receives a signal, converts the digital signal into a preset characteristic and outputs it, and converts the signal from the digital signal conversion processing unit into a pulse wave having a pulse width according to the digital amount. It is characterized by being composed of a pulse width modulation section that modulates the width and outputs a pulse signal, and a constant current circuit section that outputs a meter drive current corresponding to the pulse width of the pulse signal output from the pulse width modulation section. meter drive device.
