Ground Isolation Amplifier
BA3121F
General Description
BA3121F is a ground isolation amplifier developed for
car audio applications. This IC efficiently eliminates
problems caused by wiring resistance and removes
noise generated by other electrical devices used in
automobiles. The external capacitor values required for
this IC are so small that it allows for compact and
reliable set design.
