Quick Start List for Platform
Follow these steps when using the TPA152 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 and that the platform
power switch S1 is set to
OFF.
2) Install a TPA152 module in platform socket U5, 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 JP7 to
Lo.
5) Set Hp source switch S3 to U5 to route the output signal to the headphone
Jack (J10).

Power supply
6) Select and connect the power supply:
a) Connect an external regulated power supply set to a voltage between
4.5 V and 5.5 V to platform V
DD
power input connector J6 taking care
to observe marked polarity, or
b) Install a 5-V voltage regulator EVM (SLVP097 or equiv.) 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 ap-
propriate 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
stereo miniature phone jack J4.
9) Connect 32-
Ω
headphones to headphone jack J10.

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 should light indicating the presence of V
DD
, and the evaluation
modules installed on the platform should begin operation.
11) Adjust the signal source level as needed.
