8.4 Device Functional Modes
TPA3221 can be configured in either a stereo BTL (Bridge Tied Load) mode, mono BTL mode (only one output BTL channel active), or in a mono PBTL (Parallel Bridge Tied Load) mode. In PBTL mode the two output BTL channels are parallelled with double output current available. The parallelling of the two BTL outputs can be made either before the output LC filter, or after the output LC filter. For PBTL mode the audio performance in general be higher when parallelling before the output LC filter, but parallelling after the LC output filter can be preferred in some systems.
See Table 5-2 for mode configuration setup.
