Page 9: Description
The TPA2001D2 filterless class-D stereo audio power amplifier evaluation module is a complete, 1-W per channel class-D stereo audio power amplifier that can operate without an output filter. It consists of the TI TPA2001D2 class-D stereo 1-W audio power amplifier IC along with a small number of other parts mounted on a circuit board that measures approximately 2-1/4 inches by 1-1/2 inches (Figure 1–1 and Figure 1–2). -
Page 10: Tpa2001D2 Evm Specifications
TPA2001D2 EVM Specifications The platform has room for a single TPA2001D2 evaluation module and 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. -

Chapter 2 Operation The steps in this chapter can be followed to quickly prepare the TPA2001D2 filterless class-D audio amplifier EVM for use. Using the TPA2001D2 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. -
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. -
