I have AD8222 amplifier eval board. I want to place Buffer(voltage follower) op-amp in front on AD8222. Application is pH measurement
- I like recommendation on differential input Buffer(voltage follower) op-amp (not single input).
- Both inputs of buffer amplifier connected to + & - of pH probe. The both output of buffer amplifier connected to + & - of AD8222.
- In DIP install package if possible.
Thanks for your help in advance
