Abstract
A dual bridge amplifier includes a first bridge amplifier receiving a first input signal and having a pair of drive outputs connecting to a first load, a second bridge amplifier receiving a second input signal and having a pair of drive outputs connecting to a second load, and a mode switch between one of the drive outputs of the first bridge amplifier and one of the drive outputs of the second bridge amplifier. The mode switch closes and switches the dual bridge amplifier to a series amplification mode, based on detecting the magnitudes of the first and second input signals. The series amplification mode shares current between the first load and the second load, reducing amplifier heat generation.
