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.

Features:
- Few External Components
- No Boucherot Cells
- No Bootstrap Capacitors
- High Output Power
- No Switch ON/OFF Noise
- Very Low Stand-by Current
- Fixed Gain (30dB Stereo)
- Programmable Turn-On Delay

Protections:
- Output AC-DC Short Circuit to GND and to Supply Voltage
- Very Inductive Loads
- Loudspeaker Protection
- Overrating Chip Temperature
- Load Dump Voltage
- Fortuitous Open Ground
