2.2 Quick Start List for Platform

Follow these steps when using the TPA032D03 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 and platform power switch S1 are set to OFF.

2)Install a TPA032D03 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.

7)Connect a 12-Vregulated power supply (ensure power supply is set to OFF ) to J1, taking care to observe marked polarity.

8)Set jumper JP1 for dc source to be from input J1.

9)Set jumper JP4 for VCC power to EVMs.

10)Install a voltage regulator EVM (SLVP097) in platform socket U6.

11)Set jumper JP5 for VDD power to EVMs.

-Inputs and outputs

12)Ensure that the audio signal source level is set to minimum.

13)Connect the audio source to left and right RCA phono jacks J3 and J5 or mono miniature phone jack J4.

14)Connect 4-Ω± 8-Ωspeakers to left RCA jack J9 or to stripped wire speaker connectors J8.

-Power up

15)Verify correct voltage and input polarity and set the external power supply and platform power switch S1 to ON.

Platform LED1 and LED2 should light indicating the presence of VCC and VDD, and the evaluation module(s) installed on the platform should begin operation.

16)Set switch S2 to ON if tone control board SLOP109 is installed in U1.

17)Adjust the signal source level as needed.
