Hey I'm working on AD620 amplifier to amplify the 100mv max output of (TGS6812-D00 methane gas sensor) analog voltage to 1.1v
two supply voltages
Vs =1.1v and vs=2.3v
the pin 4 (-Vs ) will be connected to the ground
the pin 3 will be connected to the dc power supply of 2.3v
the pin 4 will be connected to the dc power supply of 1.1v
is that correct till here?
I calculated the gain and it is 11 so i need a resistor of 4.94kohm from pin 1 to pin 8 of the amplifier
I'm new with amplifier and i dont know which input of amplifier should i use (it is the inverting input or non inverting input?) and what do i do with the pin of Vreference?
and i need the voltage at the ad620 output to be positive because i'm gonna connect the output of amplifier to arduino uno
And thank you
The datasheet of the amplifier:
