Class-AB Speaker Amplifiers
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 Bi-CMOS
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=8
, 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.
