Introduction
1.2 Description
The TPA2005D1 audio power amplifier evaluation module is a complete,
low-power single-channel audio power amplifier. It consists of the TI
TPA2005D1 1.1-W low-voltage class-D audio power amplifier IC in a very
small MicroStar JuniorBGA package, along with a small number of other
parts mounted on a circuit board that is approximately one and a quarter
inches square (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. These pins allow the EVM to be plugged into the TI plug-n-play audio
amplifier evaluation platform or to be wired directly into existing circuits and
equipment when used stand-alone.

TPA2005D1 EVM Specifications
1-4
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,
andconnectsthemtoaversatilearrayofstandardaudioinputandoutputjacks
and connectors. Easy-to-use configuration controls allow the platform and
EVMs to quickly model many possible end-equipment configurations.
There is nothing to build, nothing to solder, and nothing but the speakers
included with the platform to hook up.

Operation
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
amplifierevaluation platform is aquickandeasywayto connect power,signal
andcontrolinputs,andsignaloutputstotheEVM,usingstandardconnectors.
However, the audio amplifier evaluation module can be used stand-alone by
makingconnectionsdirectlytothemodulepins,anditcanbewireddirectlyinto
existing circuits or equipment.
Theplatformswitchandjumpersettings shown in Table2–1are typical for the
TPA2005D1 EVM. They cause the TPA2005D1 amplifier IC on the EVM to
shut down when a plug is inserted into platform headphone jack J10.

Precautions
2-2
2.1 Precautions
Power Supply Input Polarity and Maximum Voltage
Always ensure that the polarity and voltage of the external power
connected to VCC power input connector J1, J2, and/or VDD 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.
Inserting or Removing EVM Boards
Do not insert or remove EVM boards with power applied—damage
to the EVM board, the platform, or both may result.

Operation
2.2 Quick Start List for Platform
Follow these steps when using the TPA2005D1 EVM with the TI plug-n-play
audio amplifier evaluation platform (see the platform user’s guide, SLOU011,
for additional details). Numbered callouts for selected steps are shown in
Figure 2–1.
-Platform preparations
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.
3) Use switch S2 to select or bypass the signal conditioning EVM (U1).
4) Set control signal polarity jumper JP8 to Lo.
5) Set jumper JP6 to select the mute control input. Jumper, J1, on the
TPA2005D1 EVM must be open to allow the TPA2005D1 to shutdown if
a plug is inserted into platform headphone jack J10.
