Headphone/Speaker amplifier for notebook PC

BH7821BFP-Y

Description

The BH7821BFP-Y is a sound amplifier developed for

notebook PCs. It includes input for SYSTEM BEEP

sound, PM BEEP sound, and SUSPEND function

required for the notebook PC.

This analog sound device is integrated into a single

chip.

Dimension

(Units:mm)

Features

1)Built-in stereo headphone amplifier applicable to

mixing input

2)Built-in BTL stereo speaker amplifier applicable to

mixing input

3)Built-in anti-pop circuit when the power is turned ON

and OFF

4)Built-in electronic volume and mute circuit

5)Low power consumption provided by the discrete

HALT mode for headphone amplifier and the

speaker amplifier (SUSPEND function)

6)Provides two systems of BEEP sound input for

notebook PCs.
