Chapter 2 Quick Start The steps in this chapter can be followed to prepare the TPA6101A2 audio amplifier EVM for use. Using the TPA6101A2 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. However, the audio amplifier evaluation module can be used stand-alone by making connections directly to the module pins, and it can be wired directly into existing circu
