I'd like to sim a load cell circuit using the following example from the AD8221 instrumentation amplifier datasheet:
Good news is that the AD8221 is included in LTSpice's library, so that simplifies things significantly. But my question is, how do I sim the load cell? How much does the upper right resistance shown in the 350Ω bridge varies under normal working conditions?
