AD623 gain problem

Dear sir, I need to amplify a signal of 0-100 mV to 0-1 V. I'm using AD623 with gain 10. + Vs=5; -Vs=0. I do not get this gain . Might be wrong ?

Thanks

What is your common mode voltage?

What is the differential voltage?

Where is the REF pin?

  • Hi harryh, i attached a schematic.

    Gain must be 10. I only get 8.5.

    Thanks for your help.

  • Miguel,

    What's the common mode voltage?  Can I assume that running on ground and 5V, the

    differential outputs sit at 2.5V and then go 50 mV up or down with pressure?
