NTE7202 Integrated Circuit 4 x 45W Quad Bridge Car Radio Amplifier Plus HSD Description: The NTE7202 is a breakthrough BCD (Bipolar/CMOS/DMOS) technology class AB Audio Power Amplifier in a 25-Lead Staggered SIP type package designed for use as an amplifier in high power car radio applications. The fully complementary P-Channel/N-Channel output structure allows a rail to rail output voltage swing which, combined with high output current and minimised saturation losses sets new power reference in the car radio field, with unparalleled distortion performance.
