Using The TPA152 EVM Stand-Alone
Using the TPA152 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 requirement exists.
Note that the mute signal applied to the EVM SD pin must be able to supply
enough current to overcome the pulldown resistor on the module (20 k
Ω
).
