10.2.2 Mono (PBTL) Systems

For the mono (PBTL) PCB layout, see Figure 87.

A mono system refers to a system in which the amplifier is used to drive a single loudspeaker. Parallel Bridge Tied Load (PBTL) indicates that the two full-bridge channels of the device are placed in parallel and drive the loudspeaker simultaneously using an identical audio signal. The primary benefit of operating the TAS5782M device in PBTL operation is to reduce the power dissipation and increase the current sourcing capabilities of the amplifier output. In this mode of operation, the current limit of the audio amplifier is approximately doubled while the on-resistance is approximately halved.

The loudspeaker can be a full-range transducer or one that only reproduces the low-frequency content of an audio signal, as in the case of a powered subwoofer. Often in this use case, two stereo signals are mixed together and sent through a low-pass filter to create a single audio signal which contains the low frequency information of the two channels. Conversely, advanced digital signal processing can create a low-frequency signal for a multichannel system, with audio processing which is specifically targeted on low-frequency effects.

Because low-frequency signals are not perceived as having a direction (at least to the extent of high-frequency signals) it is common to reproduce the low-frequency content of a stereo signal that is sent to two separate channels. This configuration pairs one device in Mono PBTL configuration and another device in Stereo BTL configuration in a single system called a 2.1 system. The Mono PBTL configuration is detailed in the 2.1 (Stereo BTL + External Mono Amplifier) Systems section. shows the Mono (PBTL) system application
