Description

1.2 Description

The TPA2000D1 filterless class-D mono audio power amplifier evaluation module is a complete, 2-W class-D audio power amplifier that can operate without an output filter. It consists of the TI TPA2000D1 class-D mono 2-W audio power amplifier IC along with a small number of other parts mounted on a circuit board that measures approximately 1-1/4 inches by 1-1/4 inches (see Figure 1–1.

Single in-line header pins extend from the underside of the module circuit board to 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.

The platform has room for two TPA2000D1 evaluation modules 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. 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

The steps in this chapter can be followed to quickly prepare the TP A2000D1 filterless class-D audio amplifier EVM for use. Using the TP A2000D1 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 stand-alone by making connections directly to the module pins, and can be wired directly into existing circuits or equipment.

The platform switch and jumper settings shown in T able 2–1 are typical for the TPA2000D1 EVM and will cause the TPA2000D1 to shut down when a plug is inserted into platform headphone jack J10.

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 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.

2.2 Quick Start List for Platform

Follow these steps when using the TPA2000D1 EVM with the TI plug-n-play audio amplifier evaluation platform (see the platform user’s guide, literature number SLOU011, for additional details). Numbered callouts for selected steps are shown in Figure 2–1 and Figure 2–2.

- 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 TPA2000D1 module in platform socket U3 or U4, 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 (causes the TPA2000D1 to shut down if a plug is inserted into platform headphone jack J10).

6) If a headphone amplifier will be installed in U5, set the headphone source switch S3 to U5.
