Using The TPA0162 EVM Stand-Alone
Using the TPA0162 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 range and the isolated OUT+ and OUT– lines for BTL operation
requirement exists.
Note that the shutdown signal applied to the EVM SHUTDOWN pin must be
able to supply enough current to overcome the pullup resistor on the module
(100 k
Ω
).
