2)Set S2 to ON when signal conditioning board is installed in U1; set S2 to OFF when no signal conditioning board is installed.
-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 TPA0253 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 Mode/Mute jumper JP6 to Mode and Polarity jumper JP8 to Hi.
-Power supply
5)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
6)Ensure that the audio signal source level is set to minimum.
7)Connect the audio source to left and right RCA phono jacks J3 and J5 or stereo miniature phone jack J4.
8)Connect the speaker to the right RCA jack J7 or to the stripped wire speaker connector J8. Make sure the speaker is connected to the Right + and ± terminals.
-Power-Up
9)Verify correct voltage and input polarity and set the external power supply
to ON. If VCC and an onboard regulator EVM are used to provide VDD, set platform power switch S1 to ON.
Platform LED2 should light indicating the presence of VDD, and the evaluation modules installed on the platform should begin operation.
10)Adjust the signal source level or adjust potentiometers R2 and R4 on the EVM as needed.
