Quick Start List for Platform

Follow these steps when using the TPA6203A1 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 TPA6203A1 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 (which causes the

TPA6203A1 to shut down if a plug is inserted into platform headphone jack
J10).

Notes:

1) X = Don’t care

2) Set S2 to ON when signal conditioning board is installed in U1; set S2 to OFF when

no signal conditioning board is installed.

Power supply

6) Select and connect the power supply:

a) Connect an external regulated power supply set to a voltage between

2.5 V and 5.5 V to platform V

DD

 power input connector J6, taking care

to observe marked polarity,
        or

b) Install a voltage regulator EVM (SLVP097 or equivalent.) in platform

socket U6. Install a 9-V battery in B1 or connect a 7 V–12 V power
source to a platform V

CC

 power input J1 or J2 and jumper the appropri-

ate power input (see platform user’s guide).

-

Inputs and outputs

7) Ensure that signal source level is set to minimum.

8) Connect the audio source to left and right RCA phono jacks J3 and J5 or

to stereo miniature phone jack J4.

9) Connect 8-

–32-

 speakers to left and right RCA jacks J7 and J9 or to

stripped wire connector J8.

-

Power Up

10) Verify correct voltage and input polarity and set the external power supply

to on. If V

CC

 and an on-board regulator EVM are used to provide V

DD

, set

platform power switch S1 to on.

Platform LED2 lights, indicating the presence of V

DD

, and the evaluation

modules installed on the platform begin operation.

11) Adjust the signal source level as needed.
