NTE1293
Integrated Circuit
Dual, Audio Power Amp, 5.8W/Ch
Description:
The NTE1293 is a dual audio power amplifier in a 12–Lead SIP type package specifically designed
for car stereo applications. This device provides an output power of 7W/Ch to a 4 load with 10%
THD at 14.4V power supply.
Features:
Very Low Number of External Components Required
Easy Mounting with No Electrical Isolation Between the Package and Heat Sink
Very Low Transient Noise at Power Switch–On
No Damage for Reverse Insertion on the PC Board
Thermal Shut–Down Circuit Included
Load Dump Protection Circuit Included
Absolute Maximum Ratings: (TA = +25 C unless otherwise specified)
