I have AD8222 amplifier eval board. I want to place Buffer(voltage follower) op-amp in front on AD8222. Application is pH measurement


  1. I like recommendation on differential input Buffer(voltage follower) op-amp (not single input).
    1. Both inputs of buffer amplifier connected to + & - of pH probe. The both output of buffer amplifier connected to + & - of AD8222.
    2. In DIP install package if possible.
