2.2 Quick Start List for Platform
Follow these steps when using the TPA6030A4EVM 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:
Note:
The TI Plug-N-Play platform sends the input signal to both the HP and LINE
inputs automatically, and only to the positive inputs. To fully take advantage
of the TPA6030A4 differential input as well as the input mode selectable mux,
the EVM should be used in a stand-alone fashion.
- 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 TPA6030A4 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 jumper JP6 to select the Mode control input.
5) Remove jumper JP5.
