2.2 Quick Start List for Platform

Follow these steps when using the TPA0202 EVM with the TI Plug-N-Play Au- dio 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 Figure 2±2, and details appear in Chapter 3.

-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 TPA0202 module in platform socket U2, 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 Hi.

5)Set jumper JP6 to select the Mode control input (causes the TPA0202 to switch to the single-ended output mode if a plug is inserted into platform headphone jack J10).

6)If the headphone Jack (J10) output will be used, set Hp source switch S3 to U2±U4.

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

7)Select and connect the power supply (ensure power supply is set to OFF ):

a)Connect an external regulated power supply set to 5 V to platform VDD power input connector J6 taking care to observe marked polarity,

or

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

U6. Connect a 7 V ± 12 V power source to a platform VCC power input J1 or J2 and jumper the appropriate power input (see platform user's

guide).

-Inputs and outputs

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

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

10)Connect 3-Ω± 8-Ωspeakers to left and right RCA jacks J7 and J9 or to stripped wire speaker connectors J8.
