10.4.2 Mono PBTL Mode

When this mode of operation is used, the two stereo outputs of the device are placed in parallel one with another to increase the power sourcing capabilities of the device. The TAS5755M supports parallel BTL (PBTL) mode with OUT_A/OUT_B (and OUT_C/OUT_D) connected before the LC filter.

The merging of the two output channels in this device can be done before the inductor portion of the output filter. This is called Single-Filter PBTL, and this mono operation is shown in Figure 58. More information about this can be found in Single-Filter PBTL Mode section.

TAS5755M Post_Filter_PBTL.gifFigure 58. Pre-Filter PBTL

On the input side of the TAS5755M device, the input signal to the mono amplifier can be selected from a mix, left or right frame from an I2S, LJ, or RJ signal. The routing of the audio data which is presented on the SPK_OUTx outputs must be configured with the PWM Output Mux Register (0x25) and PWM Shutdown Group Register (0x19).

Refer to the Mono Parallel Bridge Tied Load Application section for more details of the correct PBTL output connection of the TAS5755M.
