Ground Isolation Audio Amplifier for Automotive Applications

This Ground Isolation Amplifier is developed for car and automotive applications. The board efficiently eliminates problems caused by wiring resistance and removes noise generated by other electrical devices used in automobile environment. In a car or automotive the audio system is grounded to the car body. For this reason, electrical noise generated by the car electrical system can enter the power amplifier input through the chassis and become audible. The BA3123F utilizes the common-mode rejection characteristics of an OPAMP to eliminate this noise. 4 x RCA connectors are provided for easy audio interface. 2x pin header connector is provided for chassis ground.
