Datasheet for Ic-45w Quad Amplifier
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.
