NTE7163
Intergrated Circut
4 x 40W Quad Bridge Car Radio Amplifier
Description:
The NTE7163 is a new technology class AB audio power amplifier in a 25−Lead Staggered SIP type
package designed for high end car radio applications. Thanks to the PNP/NPN output configuration
the NTE7163 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The ex-
tremely reduced components count allows very compact sets.
