INTEGRATED CIRCUIT DEVICE AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an integrated circuit device and an electronic apparatus or the like that can perform precise analog-to-digital (A/D) conversion of a detection signal from a sensor device.SOLUTION: An integrated circuit device includes: a power supply circuit 60 that generates a power supply voltage VDDA; an A/D converter ADC to which power supply voltage VDDA is supplied from a power supply circuit 60 and which operates based on the supplied power supply voltage VDDA, and performs A/D conversion for a signal corresponding to a detection signal from a sensor device 30 within an A/D conversion range specified by the power supply voltage VDDA; and a power supply terminal PVDA to which the power supply voltage VDDA is supplied from the power supply circuit 60 and which supplies the supplied power supply voltage VDDA to the sensor device 30.
