circuit
Shutdown control pin. Pulling low the voltage on this pin shuts off the IC. In
shutdown mode, the IC only draws 1 A (typical) of supply current.
Bypass capacitor connection pin for the bias voltage generator.
Right channel input terminal
Ground connection. Connect all of the GND pins to ground plane.
Left channel input terminal
DC voltage input pin for internal volume gain setting (DC Volume control).
Output mode control input, high for SE output mode and low for BTL mode.
Left channel negative output in BTL mode and high impedance in SE mode.
Supply voltage input pin. Connect all of the VDD pins to supply voltage.
Left channel positive output in BTL mode and SE mode.
Right channel positive output in BTL mode and SE mode.
Right channel negative output in BTL mode and high impedance in SE mode.
