2.3 Quick Start List for Stand-Alone
Follow these steps to use the TPA6211A1 EVM stand-alone or when
connecting it into existing circuits or equipment. Connections to the
TPA6211A1 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
Figure 2–2.

Power supply
1) Ensure that all external power sources are set to off.
2) Connect an external regulated power supply set to 5 V to the module V
DD
and GND pins, taking care to observe marked polarity.
- Inputs and outputs
3) Ensure that the signal source level is set to minimum.
4) Connect the positive lead from the audio source to the module IN+ pin and
the negative lead to the IN– pin.
5) Connect the SHUTDOWN
pin through a normally open switch to GND.
6) Connect a 3-Ω to 32-Ω speaker to the module OUT+ and OUT– pins.
- Power Up
7) Verify correct voltage and input polarity and set the external power supply
to on.
The EVM begins operation.
8) Adjust the signal source level as needed.
