2.2 Quick Start List for Stand-Alone Operation
Follow these steps to use the TPA6017A2 EVM stand-alone or when
connecting it into existing circuits or equipment. Connections to the 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.
-
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
1) Ensure that the audio signal source level adjustments are set to
minimum.
2) Connect the right and left positive audio source to the module RIN+
and LIN+ pins, respectively. Connect the right and left negative audio
source to the module RIN– and LIN– pins, respectively.
3) If using single ended inputs, ground the LIN+ and RIN+ pins and con-
nect the signal source to RIN– and LIN–.

Evaluation Module Preparations
1) Use jumpers J1 and J2 to set the gain of the TPA6017A2 amplifier.
Refer to Table 2–2 for gain settings.
-
Control Inputs
1) SHUTDOWN: This pin is active LOW. A LOW on this pin (< 0.8 V)
shuts down the amplifier; a HIGH (> 2 V) on this pin places the amplifi-
er in the active state. Leaving this pin floating allows normal amplifier
operation in the active state.
-
Power Up
1) Verify correct voltage and input polarity and set the external power
supply to ON.
The EVM should begin operation.
2) Adjust the signal source level and gain setting jumpers, J1 and J2, as
needed.
