OK I am trying to design a circuit that uses an lm61 to monitor the temperature inside a computer case. If the temp goes over a preset value the op-amps will power a darlington array that drives a fan.
I have not gotten very far with is yet because I keep popping the lm61's. On the spec sheet it is shown connected directly to a 3-12V power source. I am using the I did that and it blew instantly. Then I tried limiting the current to around 2 mA with a 6k resistor between +12 and the lm61. Now the new lm61 wont work properly.
Can anyone tell me how to hook these things up? Do I need a minimum load on the output to get a legit output? What value resistor do I need to limit current?
I would normally keep trying but I have popped $12 worth already and have 2 left. I have tried looking for designs online that use the lm61 but I could not find anything after numerous serches and going through 50 pages of google results.
