3.4 Using The TPA0103 EVM Stand-Alone
Using the TPA0103 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 Mode A pin must be able to sup-
ply enough current to overcome the pulldown resistor on the module (100 kΩ),
possibly in parallel with a second pulldown resistor (100 kΩ).
