Set S2 to ON when signal conditioning board is installed in U1; set S2 to OFF when no signal conditioning board is installed.
Selecting and connecting the power supply:
6a. 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
6b. 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 appropriate power input (see platform user's guide).
Inputs and Outputs Setup:
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.

speakers to left and right RCA jacks J7 and J9 or to stripped wire connector J8.
Power-Up Procedure:
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.
Follow these steps to use the TPA2006D1 EVM stand-alone or when connecting it into existing circuits or
equipment. Connections to the TPA2006D1 module header pins can be made via individual sockets,
wire-wrapping, or soldering to the pins, either on the top or the bottom of the module circuit board.
Numbered callouts for selected steps are shown in
