3.4 Using The TPA0202 EVM Stand-Alone
Using the TPA0202 Audio Power Amplifier Evaluation Module stand-alone is
much the same as using it with the platform. The same 3-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 mute pin must be able to supply
enough current to overcome the pulldown resistor on the module (100 kΩ).
