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 4Ω load with 10%
THD at 14.4V power supply.
Features:
D Very Low Number of External Components Required
D Easy Mounting with No Electrical Isolation Between the Package and Heat Sink
D Very Low Transient Noise at Power Switch–On
D No Damage for Reverse Insertion on the PC Board
D Thermal Shut–Down Circuit Included
D Load Dump Protection Circuit Included
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
