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,
