NTE1285 & NTE1286
Integrated Circuit
Audio Power Amplifier, 5.8W
Description:
The NTE1285 and NTE1286 are audio power amplifiers in a 7鈥揕ead SIP type package designed es-
pecially for car radio and car stereo applications. These devices are encapsulated in newly developed
small packages featuring low thermal resistance, providing easy design for 2鈩? At 14.4V the devices
give output power of 7W with R
