10.2.2 PBTL Application
Figure 10-3 shows a schematic of a typical 2-channel solution for a head unit or external amplifier application where high power into 2 Ω is required.
Figure 10-3 Typical
2-Channel PBTL Application SchematicTo operate in PBTL mode the output stage must be paralleled according to the schematic in Figure 10-3. The device can operate in a mix of PBTL and BTL mode. This application can be set up for 3-channels, with one channel in PBTL mode and two channels in BTL mode. The device does not support a parallel configuration of all four channels for a one channel amplifier.
