Other Parts Discussed in Thread: LMC660, OPA333
Hi, I simulate an ECG machine it is work very well but whenI did it in real test it doesn't work very well i think my major problem is in right leg driver circuit. my schematic is like this picture but I used lmc660 instead of opa333, when right leg driver circuit is connected the output is full of noise but when i bypass it and just use 2.5volt aright to right leg the output is better. my question is which parameter is important for selecting suitable op-amp for right leg drive. Sincerely yours, Siyavash.
