Operation www.ti.com Power Supply A single power supply is required to power up the EVM. Since most of the pins are PVCC compliant, the PVCC supply can also be used to power the analog supply (AVCC) and can be used to pull up the logic pins for shutdown (SD) control, fault detection (FAULT), gain (GAIN0 and GAIN1), and PBTL as long as the voltage slew rate is limited to 10 V/ms.

Operation www.ti.com Table 3. TPA3113D2 Control Guide (continued) Control Function Options PBTL Sets the amplifier in PBTL mode Insert jumper to defeat PBTL If PBTL jumper is removed (PBTL mode), the Left mode and run in normal outputs (OUTPL and OUTNL) as well as the Right stereo BTL mode. outputs (OUTPR and OUTNR) are synchronized and in phase. This allows them to be connected together before the reconstruction filter for PBTL operations.
