摘要： A driver apparatus includes a vibrator and a drive circuit configured to input a drive signal to the vibrator to vibrate the vibrator. The drive circuit includes an output amplifier configured to output the drive signal to the vibrator based on a monitor signal, a power supply unit configured to supply a power supply voltage, and a power supply voltage controller configured to control the power supply voltage and to supply the controlled power supply voltage to the output amplifies. This driver apparatus can increase amplitude of the vibration of the vibrator, and can increase detection sensitivity to a physical quantity detection apparatus including the driver apparatus.
