TECHNICAL NOTE

Speaker /Headphone Amplifier Series

1W+1W Stereo Speaker /

Headphone Amplifier

BH7884EFV

●Description

The BH7884EFV is a low voltage, low noise, high output speaker and headphone amplifier drive, in which a BiCMOS

process is used. This IC supports: headphone amplifier gain adjustment, active/suspend switching, speaker amplifier

stereo/monaural switching, and amplifier mute switching. All functions are controllable from a microcontroller. Built-in digital

noise reduction circuits eliminate digital noise and BEEP sounds.

●Features

1) Built-in 1W+1W stereo speaker amplifier (Vcc=5V, RL=8Ω, THD=10%)

2) Built-in stereo headphone amplifier

3) Built-in bass boost function for speaker amplifier

4) Built-in low noise VCA (electronic volume) for headphone

5) Built-in mute circuit

6) Built-in standby circuit

7) Low current consumption specifications (9 mA TYP. in ACTIVE mode, 0.2 μA TYP. in SUSPEND mode)

●Applications

Notebook computers, LCD TVs, etc.
