[ Product 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.
