Using the TPA6011A4 EVM Stand-Alone

3.4 Using the TPA6011A4 EVM Stand-Alone

Using the TPA6011A4 audio power amplifier evaluation module stand-alone is much the same as using it with the platform. The same 4.5-V to 5.5-V power supply range and the isolated OUT+ and OUT– lines for BTL operation requirement exists.

Note that the shutdown signal applied to the EVM SHUTDOWN pin must be able to supply enough current to overcome the pullup resistor on the module (100 kΩ ).
