Shown is a typical laptop audio power amplifier integrated circuit . The audio input signals L and R that drive the speakers are sent to the audio power amplifier MAX9790A
via pins ③ and ② respectively: the audio input signals that drive the headphones are sent to
the audio power amplifier via pins @ and @, respectively, and pass through the chip internal After power amplification, the ⑥ pin, ⑦ pin and @ pin, @ pin output are used to drive the left and right channel speakers to produce
sound: the @ pin, @ pin outputs the headphone driving signal and sends it to the headphone jack.
