Hi,
I would like to make this INA works in the best range of output voltages for input differentail voltages from 40mV to 80mV.
According to datascheet I should have 100 V/V gain. It isn't true even with Vref = GND (I get G=65). I thought I have to put +3V on Vref to decrease 8V to 5V on output...
Hi
I'm designing an amplifier circuit to enable me to analyse the output from a full bridge circuit (this is a load cell on a DC supply) using the ADC of a PIC.
I'm using a INA126 amp with just a +5V supply and have set the ref input to +2.5V using a voltage ref LM336. I've found that it would...
