Chapter 2 Quick Start The steps in this chapter can be followed to quickly prepare the TPA711 MSOP audio amplifier EVM for use. Using the TPA711 MSOP EVM with the TI plug-n-play audio amplifier evaluation platform is a quick and easy way to connect power, signal and control inputs, and signal outputs to the EVM, using standard connectors. -
Page 12: Precautions
Precautions 2.1 Precautions Power Supply Input Polarity and Maximum Voltage Always ensure that the polarity and voltage of the external power connected to V power input connector J1, J2, and/or V power input connector J6 are correct. Overvoltage or reverse-polarity power applied to these terminals can open onboard soldered-in fuses and cause other damage to the platform, installed evaluation modules, and/or the power source. -
Page 13: Quick Start List For Platform
1) Ensure that all external power sources are set to OFF and that the platform power switch S1 is set to OFF. 2) Install a TPA711 MSOP module in platform sockets U3 and U4 for stereo operation (or a module in either U3 or U4 for single channel operation), taking care to align the module pins correctly. -
