I have application circuit OP-Amp for IR Thermopile but Im don’t know value ever component use in application Op-amp? and which IC Op-amp compatible use in circuit?
Please help me
Thanks
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.
