i have a graduation project i am building up an ECG and using the AD624AD instrumentation Amp , so anyone out there got any ideas for the pre-Amp or even any other amplifier or way to amplify the differencial signal and still block the CCMR
 
i have to search for a specific cct for the AD624AD which u can connect direct and you have to place an low pass filter at the end before the ADC

plz if u test post the results and the cct diagram..
 
i just did this for a project, actually. We used an instrumentation amp built from 3 op-amps and a 6th order low pass filter @ 40 Hz. The gain on the instrumentation amp was something like 1000
 
thanx 4 ur reply

i place a picture hope u can check it out ...... is it possible to run this kind of connections by the way i will use ADC at the end..............
???


plz ASAP
