Quick Start List for Stand-Alone
2.1.1
Power Supply
1) Ensure that all external power sources are set to OFF.
2) Connect an external regulated power supply, between 2.5 V and 5.5 V to
the module V
DD
and GND pins, taking care to observe marked polarity.
2.1.2
Inputs and Outputs
1) Ensure that the audio source level is set to minimum.
2) Connect the positive lead from the audio source to the module IN+ pin and
the negative lead to the IN− pin.
2.1.3
Control Inputs
1) SHUTDOWN: This pin is active low. A low on this pin shuts down the ampli-
fier; a high on this pin places the amplifier in the active state. Leaving this
pin floating also allows normal amplifier operation. Holding down switch
(S1) places the amplifier to the active state. The absolute maximum volt-
age on this terminal is VCC + 0.3 V.
2.1.4
Power Up
1) Verify correct voltage and input polarity and set the external power supply
to on.
The EVM should begin to operate.
2) Adjust the audio source level as needed.
