Audio Amplifiers FAQ
How does the second amplifier stop control function work?
Pin 6 controls the on/off state of the second amplifier, enabling switching between speaker drive (BTL) and headphone drive (SE mode).
What is the purpose of the beep signal input pin?
Pin 3 serves as the beep signal input, connected to the non-inverting input block of the first amplifier, allowing for direct beep signal generation.
