2.2 Quick Start List for Platform
Follow these steps when using the TPA2010D1 EVM with the TI Plug-N-Play
audio amplifier evaluation platform (see the platform user’s guide, SLOU011,
for additional details).
- 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 TPA2010D1 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. Jumper, J1, on the
TPA2010D1 EVM must be open to allow the TPA2010D1 to shutdown 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 (J5) or right (J3) RCA phono jacks, or both
if using two TPA2010D1 modules, or to stereo miniature phone jack (J4).
9) Connect 4-Ω to 32-Ω speakers to left (J9) or right (J7) RCA jacks, or both
if using two TPA2010D1 modules, 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.
