Page 10: Description
Description 1.1 Description The TPA3001D1 evaluation module (EVM) is a 20-W class-D mono audio power amplifier complete with a small number of external components mounted on a circuit board measuring approximately 2 1/4 inches by 1 1/2 inches (Figure 1–1 and Figure 1–2). Figure 1–1. -
Page 11: Tpa3001D1Evm Specifications
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. -
Page 13: Quick Start
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. -
