Page 11: Operation
Operation The quick start lists in this chapter contain steps that can be followed to quickly prepare the TPA6010A4 audio amplifier EVM for use either with the TI plug-n-play audio amplifier evaluation platform or for stand-alone operation. Using the EVM with the TI evaluation platform is a quick and easy way to connect power, signal and control inputs, and signal outputs to the EVM. -
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. -
