OB6220VP  TSOP28

The OB6220 Demo Board consists of a stereo 15W Bridge Tied Load（BTL）output, class-D, audio power amplifier completed with a small number of external components mounted on a printed circuit board. It can be used to directly drive speakers with an external analog audio source as the input. The audio application of 2 channels Bridge Tied Load（BTL）or 1 channel Parallel Bridge Tied Load(PBTL) are presented. The detailed features, block diagram, schematics, BOM, PCB layout, application notes and test data are described. Key Features: • Stereo 15W BTL output into 8 load at 16V • Stereo 9.4W BTL output into 8 load at 12V • Mono 30W PBTL output into 4 load at 16V • 90% efficiency(driving 8 speakers)
