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 pact and reliable set design. FApplications Car audio systems FFeatures
1) Large capacitors not required 2) High mon-mode rejection ratio (57dB typ. at f = 1kHz). 3) Low noise (VNO = 3.5µVrms Typ.)....
