2.2 Quick Start List for Platform
Follow these steps when using the TPA6010A4 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 Figure 2–2.
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 TPA6010A4 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 TPA6010A4
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 headphone source
switch S3 to U2–U4.

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
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 V
DD
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 V
CC
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) If PCBEEP is to be used, a dc-blocked 1-V p–p 1-kHz square wave may
be applied to the EVM PCBEEP test point (TP1). (See the TPA6010A4
audio amplifier data sheet (TI lit number SLOS268) for more information.)
11) Connect the outputs:
a) Connect speakers to left and right RCA jacks J7 and J9 or to stripped
wire speaker connectors J8.,
and/or
b) Connect a line-level load to the EVM LDOCK and RDOCK terminals
that is no less than 1-k
Ω
and is dc-blocked.
