INA317: GAIN OF AMPLIFIER - ISSUE | INA317

Pedro Santos
Prodigy 10 points
Part Number: INA317

Tool/software:

Hi, 

I have an application that involves amplifying a signal coming from a wheatstone bridge. I'm using the INA317, for differential amplification.

The supposed gain is 1+(100/1.43) = 70.9 =G
I'm having problems with the amp output, because I have an input signal of 3.65mV and the output has only 103mV. Below I present the circuit?!


What's my mistake?

Thanks, Pedro Santos
