Alternative to AD623


I tried several models for my design (put under NDA). Best result was with AD623. However, I wonder if there is an instrumentation amplifier with the same architecture as AD623 is available with less noise.

What I believe to be needed is not normal instrumentation amplifier as even AD8229  and AD620 were unable to capture the signal like AD623.

Your help is highly appreciated. Thanks

  • Thanks Emman for your response. I tried AD8422 upon recommendation but unfortunately it showed more oscillations when an impulse is applied unlike AD623. Kindly keep this post opened as I ordered AD8223 to evaluate. I will give you my feedback upon testing it in few days. Thanks again for your prompt response.
