Ground Isolation Amplifier - BA3121F

This IC is ground isolation amplifiers developed for use in car audio applications. This IC efficiently eliminates problems caused by wiring resistance, and removes noise generated by the electrical devices used in automobiles. The capacitance values of the external capacitors required for the ICs are small, in order to allow compact and reliable set design.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
