Chapter 2 Operation Follow the steps in this chapter to quickly prepare the TPA6110A2 MSOP audio amplifier EVM for use. The TPA6110A2 MSOP EVM and the TI plug-n-play audio amplifier evaluation platform provide 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 can be wired directly into existing circ
