BA7787FS - Headphone / speaker amplifier for notebook computers

Datasheet Summary

Description

Pin No.

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 amplifier and speaker amplifier, for low-power-consumption computers . 5) Two beep input pins, a necessity for notebook compute.
