2.2 Quick Start List for Platform
Follow these steps when using the TPA6203A1 EVM with the TI
-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 TPA6203A1 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 (which causes the TPA6203A1 to shut down if a plug is inserted into platform headphone jack J10).
Table 2–2. Platform Jumper and Switch Settings for the TPA6203A1 EVM
EVM | JP6 | JP7 | JP8 | S2 | S3 |
TPA6203A1 | Mute | X | Lo | See Note 2 | X |
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 VDD 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
source to a platform VCC 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 and right RCA phono jacks J3 and J5 or to stereo miniature phone jack J4.
9)Connect
-Power Up
10)Verify correct voltage and input polarity and set the external power supply
to on. If VCC and an
Platform LED2 lights, indicating the presence of VDD, and the evaluation modules installed on the platform begin operation.
11) Adjust the signal source level as needed.
