DESCRIPTION
I Mono input terminal
I SHUTDOWN places the entire device in shutdown mode when held low. TTL compatible input.
I VDD is the supply voltage terminal.
I BYPASS is the tap to the voltage divider for internal mid-supply bias. This terminal should be connected
to a 0.1-µF to 1-µF capacitor.
I Right-channel input terminal
O Right-output in SE mode and mono positive output in BTL mode
I Selects between stereo and mono mode. When held high, the amplifier is in SE stereo mode, while held
low, the amplifier is in BTL mono mode.
Ground terminal
I Left-channel input terminal
O Left-output in SE mode and mono negative output in BTL mode.

§ _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
