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
FFeatures
1) Large capacitors not required
2) High common-mode rejection ratio
