NTE1285 & NTE1286
Integrated Circuit
Audio Power Amplifier, 5.8W
Description:
The NTE1285 and NTE1286 are audio power amplifiers in a 7–Lead 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. At 14.4V the devices
give output power of 7W with RL = 4and 11W with RL = 2.
Features:
D High Output Power
D Low Transient Noise at Power Supplu Switch ON
D Mirror Image Pin Configurations
D Protection Circuits are Provided for the Following:
Load Dump Protection
Thermal Shut–Down Protection
Overvoltage Protection
Output Terminal Short–Circuit Protection
