2.3 Quick Start List for Stand-Alone
Follow these steps to use the TPA0211 EVM stand-alone or when connecting
it into existing circuits or equipment. Connections to the TPA0211 EVM 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.

Due to the very small size of the MSOP IC package, the standard part number TPA0211 is replaced with the code TIAEG
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 VDD
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 audio source to the module IN and GND pins, taking care to
observe marked polarity.
5) Connect the SHUTDOWN pin to V
DD
through a normally closed switch.
6) For BTL output, connect a 4-Ω – 32-Ω speaker to the module OUT+ and
OUT– pins, or
7) For single-ended output, connect a headphone or a 4-Ω – 32-Ω speaker
to the module OUT+ and GND pins through a 33 µF to 1000 µF output-
coupling capacitor (Figure 2–4).
Power-up
8) Verify correct voltage and input polarity and set the external power supply
to
ON.
The EVM should begin operation.
9) Adjust the signal source level and module gain (via R3) as needed.
