9.3.7 PBTL Select

The TPA3138D2 device offers the feature of Parallel BTL operation with two outputs of each channel connected directly. Connecting LINP and LINN directly to Ground (without capacitors) sets the device in Mono Mode during power up. Connect the OUTPR and OUTNR together for the positive speaker terminal and OUTNL and OUTPL together for the negative speaker terminal. Analog input signal is applied to INPR and INNR. For an example of the PBTL connection, see the schematic in the Typical Applications section.
