I
Connect ADD0 and ADD1 to GND for stand-alone mode.
Analog Ground. Ground connection for the input bias and gain circuits.
Right Audio Negative Output. Each output is current limited.
Right Audio Positive Output . Each output is current limited.
Power Ground. Ground connection for the output stage drivers.
Charge-Pump Output (When Charge Pump is On; CPOFF = 0). When the charge pump is off,
provide an external supply through a diode to the CHOLD input. Bypass CHOLD with 1µF to PGND.
Left Audio Negative Output. Each output is current limited.
Left Audio Positive Outputs. Each output is current limited.
Charge-Pump Flying Capacitor, Positive Connection
Charge-Pump Flying Capacitor, Negative Connection
Open-Drain Fault Flag Output. FLAG indicates a fault on any one channel. In stand-alone mode,
FLAG is stretched to a typical pulse width of 100ms.
Soft-Start Capacitor Connection. CSS is charged/discharged by < 100FA current to get soft mute/
play transition. Bypass to GND through a 220nF capacitor.
Exposed Pad. Connect to PGND.
