Operation www.ti.com 2 Operation 2.1 Quick-Start List for Stand-Alone Operation Follow these steps to use the TPA3117D2EVM for stand-alone operation or when connecting it into existing circuits or equipment. Connections to the EVM power supply and output connectors can be made by inserting stripped wire. The input connectors are RCA phono jacks. 2.1.1 Power Supply A single power supply is required to power the evaluation module (EVM).

Schematic, Layout, and Bill of Materials www.ti.com Table 3. TPA3117D2 Control Guide (continued) Control Function Options Notes PBTL Sets the amplifier in mono PBTL mode when removed Insert jumper to defeat PBTL mode and run in normal stereo BTL mode If PBTL jumper is removed (PBTL mode), the left outputs (OUTPL and OUTNL) as well as the right outputs (OUTPR and OUTNR) are synchronized and in phase. This allows them to be connected together before the reconstruction filter for PBTL operation.
