I am using the LT1168 instrumentation amplifier for my project and I am trying to figure out how to make it work with a Li-Poly 3.7 Volts battery. I am not able to understand the single supply operation theory from the datasheet. I have given +3.7 volts to the V+ pin and the V- pin is grounded but I am unsure what has to be given to the Ref pin of the opamp.
Here's the link to the datasheet: http://cds.linear.com/docs/en/datasheet/1168fa.pdf
It would be really helpful if you guys can kindly help me with the connections to make it work with a single supply. Thanks.
