(see Figure 1–1). Figure 1–1. The TI TPA2005D1 Audio Amplifier Evaluation Module † Due to the very small size of the MicroStar Junior BGA IC package, the standard part number TPA2005D1 is replaced with the code PB051. Single in-line header pins are mounted to the underside of the module circuit board. -
Page 12: Tpa2005D1 Evm Specifications
TPA2005D1 EVM Specifications The platform, which has room for a pair of TPA2005D1 evaluation modules, 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: Operation
Chapter 2 Operation Follow the steps in this chapter to prepare the TPA2005D1 audio amplifier EVM for use. Using the TPA2005D1 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. -
Page 14: 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. -
Page 15: Quick Start List For Platform
1) Ensure that all external power sources are set to off and that the platform power switch S1 is set to off. 2) Install a TPA2005D1 module in platform sockets U3 and U4 for stereo operation (or a module in either U3 or U4 for single channel operation), taking care to align the module pins correctly. -
