Multimedia ICs Microphone Amplifier BA7760 / BA7760F 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 input.
