Hi,
I am having an issue with an amplifier, more precisely with an instrumentation amplifier INA333. I want a gain to be around 500 and that is the reason I put a resistor of 200ohm between pins 1 and 8. Voltage between two input pins equals around 0.0027 V and output is around 1.06 V, but according to my calculation 0.0027*500 equals 1.35 V.
Does anybody have a suggestion how to calibrate this amplifier?
