Hi,

I'm using AD8422 to amplify the siganl from bridge circuit.

when I/P voltage 5V,RG = 301 ohm i see the output amplified linearly.

for 0KG on bridge ckt = 0.3824V

     1KG                 = 0.5089

      2kG   = 0.6350

       3Kg = 0.7611

 

But for RG = 100 ohm

0KG = 2.2815

1KG = 3.0088

2Kg = 3.7405

3kg = 3.4270

 

Here i see at 3kg weight output dicerases.

I tried with changing input supply by 3V also but same behavior.

Kindly help. thank you.
