NTE1392 & NTE1393
Integrated Circuit
Audio Power Amp, 7W
Description:
The NTE1392 and NTE1393 are class B power amplifiers in a 10–Lead SIP type package designed
especially for home tpe stereo amplifiers. These devices provide an output power of 5W at 19V, and
also 7W at 22V to an 8Ω load with 10% distortion.
