Description:

Ground isolation amplifier

Features

* 1) Large capacitors not required 2) High common-mode rejection ratio (57dB typ. at f = 1kHz). 3) Low noise (VNO = 3.5µVrms Typ. ). FAbsolute maximum ratings (Ta = 25_C) 4) Low distortion (THD = 0.002% Typ. ). 5) Two channels. FRecommended operating conditions (Ta = 25_C) 717 Audio ICs FBlock diagr

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
