NTE7053
Integrated Circuit
22W Bridge鈥揝tereo Amplifier
for Car Radio
Description:
The NTE7053 is an audio power amplifier is a 11鈥揕ead Staggered SIP type package designed for car
radio applications.
Thanks to the fully complementary PNP/NPN output configuration, the high performance of this de-
vice is obtained without bootstrap capacitors.
A delay turn鈥搊n mute circuit eliminates audible ON/OFF noise, and a novel short circuit protection
system prevents spurious intervention with highly inductive loads.
