I need to amplify the strain gauge of 330 Ohm. I gave VS= 10v and Ref Voltage as 0.926 and RG= 100Ohm Preset, Can i connect strain gauge directly to Pin 2 and 3 or I need to connect using whetstone Bridge ? pls guide
Sounds like you are intending to use the amplifier with a gain factor of 1000. For many reasons, including sensitivity, robustness and just simply proper operation of the amplifier, you will want to use a bridge circuit. For a detailed explanation and bridge circuit techniques, please refer to sections 3-4 and 3-5 of the Basic Linear Design book which can be found here.
