2.3 Quick Start List for Stand-Alone
Follow these steps to use the TPA005D02 class D EVM stand-alone or to
connect it into existing circuits or equipment. Connections to the TPA005D02
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.
- 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. Separate right
channel and left channel VDD supplies can be connected, or a single
supply can be used for both.
- Inputs and outputs
3) Ensure that audio signal source level adjustments are set to minimum.
4) Connect the audio source to the module RIN+/RIN– and LIN+/LIN– pins,
taking care to observe marked polarity.
5) Connect a control signal to the module MUTE pin, if necessary. The control
signal should be high or floating for normal operation and low to mute the
module.
6) Connect a 4-
Ω
– 8-
Ω
speaker (use 4-
Ω
for best performance) to the
module ROUT+/ROUT– pins and another speaker to the LOUT+/LOUT–
pins, taking care to observe marked polarity.
- Power-up
7) Verify correct voltage and input polarity and set the external power supply
to ON.
The EVM should begin operation.
8) Adjust the signal source level as needed.
