Op-Amps for ECG Monitor

  1. Jun 25, 2006 #1
    Dear Forum,

    I would like to build my own ECG monitor.
    Does anyone have experience building one?

    Especially I am looking for recommendations on which op amps I can use. The ones I have found, like TI's ina122, ina 332 are both rather expensive (like 10 euro per piece) and hard tu find through the regular distributors.


    regards
    t.

    What are the specs that you are looking for from your opamp components? What CMRR and PSRR? What input impedance and input output voltage characteristics? What are you going to use for supplies?
