摘要 |
The present invention discloses a load driving circuit, comprising a voltage differential generation circuit and a common mode voltage generation circuit; wherein the voltage differential generation circuit is configured to generate a driving voltage for driving a load; and the common mode voltage generation circuit is configured to: when the voltage differential generation circuit generates the driving voltage for driving the load, regulate the voltages output by a first output terminal and a second output terminal of the voltage differential generation circuit to the same voltage value. The present invention also provides a load driving method and application devices thereof. With the technical solutions according to the present invention, a central value of a voltage output by the first output terminal and a voltage output by the second output terminal of the voltage differential generation circuit is effectively regulated. In this way, when a duty cycle of an input signal is within a range of 0 to 100%, the driving voltage generated by the voltage differential generation circuit is in a linear relation with the duty cycle of the input signal, thereby ensuring fidelity of an output signal. |
