Audio ICs

Ground isolation amplifier

BA3121 / BA3121F / BA3121N

The BA3121,BA3121F and BA3121N are ground isolation amplifiers developed for use in car audio applications. These

ICs efficiently eliminate problems caused by wiring resistance, and remove noise generated by the electrical devices

used in automobiles. The capacitance values of the external capacitors required for the ICs are small to allow compact

and reliable set design.

FApplications

Car audio systems
