NTE1389
Integrated Circuit
Dual, Audio Power Amplifier, 20W
Description:
the NTE1389 is an audio power amplifier in a 12鈥揕ead 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.
