2.3 Quick Start List for Stand-Alone
Follow these steps to use the TPA6101A2 EVM stand-alone or when connect-
ing it into existing circuits or equipment. Connections to the TPA6101A2 mod-
ule header pins can be made via individual sockets, wire-wrapping, or solder-
ing 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 TPA6101A2 is
replaced with the code TIAJM.
- Power supply
1) Ensure that all external power sources are set to OFF.
2) Connect an external regulated power supply set between 1.6 V and 3.3 V
to the module VDD and GND pins taking care to observe marked polarity.
- Inputs and outputs
3) Ensure that signal source level is set to minimum.
4) Connect the shutdown pin to V
DD
through a normally open switch.

7) Verify correct voltage and input polarity and set the external power supply
to ON.
The EVM should begin operation.
