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:
D Can be used as OCL Connection
D Very Low Output Offset Voltage
D High Output Power
D Very Low Distortion
D Very Low Number of External Low Size Components, Very Simple Mounting System with no
Electrical isolation Between the package and the Heat Sink
D Low Thermal Resistance
D Provides the Following Protective Circuits:
Load Dump Protection
Output Thermal Short Circuit Protection
Thermal Shutdown Protection
Speaker Protection
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
