Abstract
There are provided an actuator driving apparatus, a camera module, and an electronic apparatus to selectively use a position and current control method and a current control method. The actuator driving apparatus includes a position controller and a current driver. The position controller is configured to receive a control input signal and output the control input signal or a position control signal, which is generated based on the control input signal, according to a mode signal. The current driver is configured to generate a current to drive an actuator according to the control input signal or the position control signal.
