Using The TPA701 MSOP EVM Stand-Alone

3.4 Using The TPA701 MSOP EVM Stand-Alone

Using the TPA701 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 range and the isolated OUT+ and OUT± lines for BTL operation requirement exists.

Note that the mute signal applied to the EVM shutdown pins must be able to supply enough current to overcome the pulldown resistors on the modules (20 kΩ 20 kΩ for two EVMs).

² Due to the very small size of the MSOP IC package, the standard part number TPA701 is replaced with the code TIABA.
