Abstract
A power amplifier includes: at least two first bridge type amplifying circuits and at least two second bridge type amplifying circuits; the negative pole of the first load of each first bridge type amplifying circuit is respectively coupled to the positive stage of the second load of each second bridge type amplifying circuits through a gating circuit. When both a first input signal input into one of the at least two first bridge type amplifying circuits and a second input signal input into one of the at least two second bridge type amplifying circuits are less than a preset threshold, the gating circuit is turned on, so that the one of the at least two first bridge type amplifying circuits and the one of the at least two second bridge type amplifying circuits can share load current by the gating circuit.
