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