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 de-

vice 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.

Features:

D Few External Components

D No Boucherot Cells

D Output AC–DC Short Circuit to GND and to

Supply Voltage

D Very Inductive Loads

D No Bootstrap Capacitors

D High Output Power

D Loudspeaker Protection

D Overrating Chip Temperature

D Load Dump Voltage

D No Switch ON/OFF Noise

D Very Low Stand–by Current

D Fixed Gain (30dB Stereo)

D Programmable Turn–On Delay

D Fortuitous Open Ground
