NTE1389
Integrated Circuit Dual, Audio Power Amplifier, 20W

Description:
the NTE1389 is an audio power amplifier in a 12-Lead SIP type package specifically designed for car stereo applications. Typically, it provides 23W output power at 14.4V and 20W at 13.2V on a 4 Ohm load.
This device can be used without capacitors because it incorporates the original short circuit protection which protects output power transistors and a speaker at the same time when the output terminal is shorted to ground.

Features:
- Can be used as OCL Connection
- Very Low Output Offset Voltage
- High Output Power
- Very Low Distortion
- Very Low Number of External Low Size Components, Very Simple Mounting System with no Electrical isolation Between the package and the Heat Sink
- Low Thermal Resistance
- Provides the Following Protective Circuits:
Load Dump Protection
Output Thermal Short Circuit Protection
Thermal Shutdown Protection
Speaker Protection
