Abstract:
A driver circuit includes a first operational amplifier circuit, a second operational amplifier circuit, and at least one power switching circuit is provided. The first operational amplifier circuit receives a first input signal and generates a first output signal according to the first input signal. The second operational amplifier circuit receives a second input signal and generates a second output signal according to the second input signal. The at least one power switching circuit is coupled to the first operational amplifier circuit and the second operational amplifier circuit, and configured to switch at least one power supply for both the first operational amplifier circuit and the second operational amplifier circuit.
