Zusammenfassung:PCT No. PCT/US96/08826 Sec. 371 Date Jul. 27, 1998 Sec. 102(e) Date Jul. 27, 1998 PCT Filed Jun. 5, 1996 PCT Pub. No. WO96/41412 PCT Pub. Date Dec. 19, 1996A monolithic integrated circuit is mounted in a speaker cabinet to drive the voice coil of the speaker. The monolithic integrated circuit may be a class D amplifier and is at least a half bridge or full bridge power MOSFET device. Structures comprise MOS switching devices of the bridge driver and N+ buried layer of the QVDMOS transistors of the bridge circuits.
