2.2 Quick Start List for Platform
Follow these steps when using the TPA005D12 class-D 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 and details appear in Chapter 3.
- Platform Preparations
1) Ensure that all external power sources are set to OFF.
2) Install a TPA005D12 module in platform socket U2, taking care to align the
module pins correctly (EVM power pins engage sockets U2 and U3).
3) Set switch S2 to OFF.
4) Set switch S3 to U5.
5) Set jumper JP6 to select the Mute control input.
6) Set control signal Polarity jumper JP8 to Lo.

Notes: 1) ON = Jumper installed, OFF = Jumper NOT Installed, X = Don’t care
2) Unregulated and battery sources must have a voltage regulator EVM (SLVP097) installed in platform socket U6.
3) Set to ON when tone control board SLOP109 is installed in U1.
- Power supply
7) Connect a 5-V regulated power supply (ensure power supply is set to
OFF ) to J6, taking care to observe marked polarity.
8) Set jumper JP5 for VDD power to EVMs.
- Inputs and outputs
9) Ensure that the audio signal source level is set to minimum.
10) Connect the audio source to left and right RCA phono jacks J3 and J5 or
stereo miniature phone jack J4.
11) Connect 4-

speakers to left and right RCA jacks J7 and J9 or to
stripped wire speaker connectors J8.
- Power up
12) Verify correct voltage and input polarity and set the external power supply
to ON.
Platform LED2 should light indicating the presence of V
DD
, and the evaluation
module(s) installed on the platform should begin operation.
13) Set switch S2 to ON if tone control board SLOP109 is installed in U1.
14) Adjust the signal source level as needed.
