3.4 Using The TPA122 MSOP EVM Stand-Alone

Using the TPA122 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 requirement exists.

Note that the shutdown signal applied to the EVM SD pin must be able to supply enough current to overcome the pulldown resistor on the module (20 kΩ).
