2 Setup By Mode
The following sections describe the setup and configuration for each output mode. The TPA3223EVM allows for
two output modes: Stereo BTL and Mono PBTL.
2.1 BTL MODE (Stereo - 2 Speaker Outputs)
This mode is the same as described in Quick Start (BTL MODE) .
2.2 PBTL MODE (Mono – 1 Speaker Output)
This mode provides one speaker output that is more powerful than each BTL output and is useful when mono
audio is to be played or when more power is needed.
Figure 2-1 illustrates the PBTL mode output configuration with 4 inductors.
