SLOS882A â JANUARY 2015 â REVISED APRIL 2015
11 Application and Implementation
11.1 Application Information
The TPA3140D2 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 TPA3140D2 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 AGL or PLIMIT circuit can be used to
control system power, see functional description of these features.
