Using The TPA711 MSOP EVM Stand-Alone
Using the TPA711 MSOP audio power amplifier evaluation module
stand-alone is much the same as using it with the platform. The same 2.5-V
to 5.5-V power supply range and the isolated OUT+ and OUT– lines for BTL
operation requirement exists.

Note that the mute signal applied to the EVM shutdown pins must be able to
supply enough current to overcome the pulldown resistors on the modules
