reverse Posted February 13, 2005 Share Posted February 13, 2005 Will I fry this integrated circuit. Just made up a custom circuit and the integrated circuit (some sort of amplifier) is running at 40 deg Cel. can they run that hot? I can cool it with a fan, but do I need to?

RICHARDBATTY Posted February 13, 2005 Share Posted February 13, 2005 What codes are on the chip. Does it have a heat sink. How and with what did you measure the temperature. Link to comment Share on other sites More sharing options...
reverse Posted February 13, 2005 Author Share Posted February 13, 2005 No Code but Similar to a lm324n I would think by its position. No heatsink. A non contact infrared thermometer. Link to comment Share on other sites More sharing options...
RICHARDBATTY Posted February 13, 2005 Share Posted February 13, 2005 I think that one would run ok to about 65 degrees c. Did you check the components in the circuit you took the chip from. If your using the same ones at the same supply volts you should be ok. Whats the circuit for. Link to comment Share on other sites More sharing options...
reverse Posted February 14, 2005 Author Share Posted February 14, 2005 Hey thanks for the help . Problem solved. Found a part in the circuit where a back feeding potential of a few volts was causing the heating effect. Put a diode in and hey-presto, the IC went down to ambient temperature. Thanks again. ps it's a sound generator to emulate the background sound of a battleship in transit. Link to comment Share on other sites More sharing options...
Lance Posted February 14, 2005 Share Posted February 14, 2005 Next time you can look up the data sheet and it will tell you what temperature you can run it at. Link to comment Share on other sites More sharing options...
