TPA3001D1EVM Specifications The platform, which has room for a single TPA3001D1EVM, is a convenient vehicle for demonstrating TI’s audio power amplifier and related evaluation modules. The EVMs simply plug into the platform, which automatically provides power to the modules, interconnects them correctly, and connects them to a versatile array of standard audio input and output jacks and connectors. Easy-to-use configuration controls allow the platform and EVMs to quickly model many possible end-

Chapter 2 Follow the steps in this chapter to quickly prepare the TPA3001D1EVM for use. Using the TPA3001D1EVM 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 in stand-alone operation by making connections directly to the module pins, and it can be wired directly into existing circuits or
