hiii..
the following circuit is so strange..it was working so fine but after i just added a cap in the input ,the voltage just after the cap became so so strange and sure not logic
notes
1- changing the cap value doesn't change such huge strange offset
2- in the image below Rin , Cin is the input Z of the Instrument Amp.
3- AD623 is Instumention Amp. with very high Zin ( 2G||2p) from datasheet
Please I need your help
also if any one has another way to remove the offset 500mv from the input , plz express it
