10 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

10.1 Application Information

The TPA3136D2, TPA3136AD2 device is designed for use in inductor free applications with limited distance wire

length) between amplifier and speakers like in TV sets, sound docks and Bluetooth speakers. The TPA3136D2,

TPA3136AD2 device can either be configured in stereo or mono mode, depending on output power conditions.

Depending on output power requirements and necessity for (speaker) load protection, the built in PLIMIT circuit

can be used to control system power, see functional description of these features.
