We want to used AD8293G80 for current sensing application and We tried to follow schematic of datasheet page 12. But we got opposite direction of current from AD8293G80.(Vout is 2.xV). Does there have tyro of datasheet?
Looking at the schematic, the REF pin of AD8293G80 is tied up to the reference pin of the ADC which has a 3.3V. It make sense to me that the direction of the current on the input pin is reverse. The transfer function of the inamp circuit in figure 21 is like this: Vout = Vref + (-Ishunt x Rshunt)(G). This shows that when Ishunt is 0mA, output of the inamp is 3.3V (full scale). As Ishunt increases, the output of the inamp decreases.
I hope this helps. Let me know if you need anything else.
