I am kinda frustrated that I cannot meet the requirement of all the instrumentation amplifier (Analog devices product) that I have bought.
I have two input signal:
In+ = DC signal anywhere from 400mV to 700mV
In- = DC signal anywhere from 100mV to 300mV
Power supply: 9V single supply
Common Mode Voltage: I do not know. How do you determine that?
I have used differential amplifier using LTC6800, with a gain of 6, and it works fine.
I want like to use an instrumentation amplifier instead of differential amplifier, and ask you for help. I have tried using diamond plot calculator, and I don't get it.
Can you please recommend me an instrumentation amplifier?
