Quick Start

Evaluation Module Preparations
6) To allow the module SE/BTL control input to switch the amplifier IC
between single ended (SE) and bridge-tied load (BTL) output modes, set
output mode jumper J1 to
OFF. To keep the module amplifier IC in the
single-ended output mode regardless of the control input state, set jumper
J1 to
ON.
7) When the module powers up or comes out of shutdown, the volume is set
at the –85 dB level. Press the UP pushbutton, S2, until the desired volume
level is reached.

Control Inputs
8) Connect control lines to the various module control input pins as needed:
a) SE/BTL: A high selects the single-ended (SE) output mode; a low or
float selects the bridge-tied load (BTL) output mode.
b) SHUTDOWN: A low shuts down the amplifier IC on the module; a high
or float allows normal operation.

Power Up
9) Verify correct voltage and input polarity and set the external power supply
to
ON.
The EVM should begin operation.
10) Adjust the signal source level as needed.
