I am working on sensor read out circuit.
I want to make first version on the breadboard before I make PCB.
I am looking for discrete component instrumentation amplifier that has same capability as AD8422.
Does anyone can give me some options or how can I find them?
Or, if there is no discrete instrumentation amplifier,
Can you guys give me some op-amp options I can choose to build the circuit?
In that case I may need 3 op-amp for instrumentation amplifier and need low-pass filter and another gain stage.
I am kinda new for this, and do not know what amplifier I need to get proper output with breadboard level circuit.
thanks for your help.
