Inverting Left-Channel Audio Input
Amplifier Signal Ground. The noninverting inputs of the amplifiers are connected to the amplifier
signal ground. Connect both to the signal ground plane.
Inverting Right-Channel Audio Input
Amplifier Positive-Power Supply. Connect to positive supply. Bypass with a 1µF capacitor to
SGND as close to the pin as possible.
Active-Low Shutdown Input
Charge-Pump Power Supply. Powers charge-pump inverter, charge-pump logic, and oscillator.
Connect to positive supply. Bypass with a 1µF capacitor to PGND as close to the pin as possible.
Flying-Capacitor Positive Terminal. Connect a 1µF capacitor between C1P and C1N.
Power Ground. Connect both to the power ground plane.
Flying-Capacitor Negative Terminal. Connect a 1µF capacitor between C1P and C1N.
