| You need an op amp with low offset error, since the thermopile is a very low voltage. Lowest you'll ever find is a chopper op amp, externally they have the same operation & pinout as a normal op amp. LTC1013 is one of the best choppers available, probably much better than you need. http://www.linear.com/pc/productDeta...09,C1021,P1222 Use precision resistors too. | |
