Abstract
A self-configurable, dual bridge, power amplifier has a window comparator to sense amplifier signals and control a plurality of configuring switches capable of configuring the amplifier either as a single bridge amplifier driving two loads connected in series or as two distinct bridge amplifiers each driving one of the two loads. When the two amplifier signals remain within a range defined by a negative voltage reference and a positive voltage reference, the amplifier is configured as a single bridge driving the two loads in series, thus reducing power dissipation. Several embodiments of the invention are shown.
