Abstract:
A full-bridge class-D amplifier circuit comprises first through fourth power devices. First conduction terminals of the first and third power devices are coupled to a first power supply voltage, and second conduction terminals of the second and fourth power devices are coupled to a second power supply voltage. A second conduction terminal of the first power device and a first conduction terminal of the second power device are coupled to a first amplifier output. A second conduction terminal of the third power device and a first conduction terminal of the fourth power device are coupled to a second amplifier output. Left and right driver devices respectively disposed adjacent to left and right sides of the first power device have outputs respectively coupled to left and right control terminals respectively disposed on the left and right sides of the first power device.
