The BA7760 and BA7760F are dual microphone amplifiers designed for audio signal amplification. These are low noise amplifiers with a low -122dBV (typically) equivalent input noise voltage. Each IC has an internal mixer buffer amplifier for the mixing of signals from two channels. When used with the BA7725S or BA7725FS, the BA7726AS or BA7726AFS and BU9252S or BU9252F, these ICs simplify the configuration of digital echo systems with two inputs (for karaoke duets, for instance).

FEATUREs
1) Internal 2-channel low noise microphone amplifier.
2) Internal mixer buffer amplifier with mute function.
3) Available in 2 types of packages: DIP 14-pin or SOP 14-pin.

APPLICATIONs
    Audio equipment with karaoke features, VCRs, LDs, etc.
