Abstract:
1. A stereo class-D audio system comprising: four NMOS high-side devices; four NMOS low-side devices; a source of each high-side device being connected to a drain of a respective low-side device to form four half-bridge circuits with the four half-bridge circuits grouped as two half-bridge pairs, each half-bridge circuit haying an output node at the sourced of its high-side device and the drain of its low-side device; a package containing the two half-bridge pairs; and a set of electrical contacts for connecting the class-D audio system to an external circuit, the set of electrical contacts including at least one supply contact and at least one ground contact for each of the two half-bridge pairs, the supply contact of each half-bridge pair connected to the drains of the NMOS high-side devices within that half-bridge pair and the ground contact of each half-bridge pair connected to the sources of the NMOS low-side devices within that half-bridge pair, the electrical contacts also including at least one output contact for each output node of each half-bridge circuit.
