BA3121F-E2

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.
