I am attempting to simulate a circuit in TINA with gain of 10 using the resistor values suggested on page 21 of the datasheet.  However, both these resistors and the resistors in the equations are labeled with numbers while the corresponding figures are labeled Rg, Rs, Rf, and Rt.  How do they correlate?  Also, this is my first time using TINA: how do I get the voltage generator to simulate a voltage from 0 to 20mV at only one input?

    Hi Angela,
    I am using FIgure 77 nomenclature.
    I agree it is hard to figure out the resistor numbers, but here is the solution: R2 and R4 are RF1 and RF2; R1 is RG2; R3 is RG1 and RT is RT.

    This is for a single ended input. Are you using a single ended input or differential input?

    Regards,
