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.
·Built-in 1W+1W stereo speaker amplifier (Vcc=5V, RL=8O, THD=10%)
·Built-in stereo headphone amplifier
·Built-in bass boost function for speaker amplifier
·Built-in low noise VCA (electronic volume) for headphone
·Built-in mute circuit
·Built-in standby circuit
·Low current consumption specifications (9 mA TYP. in ACTIVE mode, 0.2 µA TYP. in SUSPEND mode)
