It is equal to R1 for the inverting input and it is R3 + R4 for the non-inverting input. You can make both input resistances high and equal... and also to adust the gain only by one resistor with a 3-opamp circuit of a more sophisticated differential amplifier known as "instrumentation amplifier". | |
