notebook computers

BA7786FP-Y / BA7787FS

The BA7786FP-Y and BA7787FS are sound amplifiers designed for notebook computers, and contain a suspend

function and input pins for the system beep and PM beep sounds used by notebook computers. In short, this single-

chip IC contains all the analog audio components needed for notebook computers.

•Features

1) Stereo headphone amplifier that supports mixing

input, along with a stereo speaker amplifier

(BA7786FP-Y) or BTL monaural speaker amplifier

(BA7787FS).

2) Internal anti-pop circuit, to prevent the popping sounds

that occur when the power is turned on and off.

3) Internal electronic volume switch and mute circuit.

4) Separate suspend modes for the headphone amplifi-

er and speaker amplifier, for low-power-consumption

computers .

5) Two beep input pins, a necessity for notebook com-

puters.
