Figure 6 shows an in-amp circuit that has the obvious advantage
of requiring only one AD706, rather than three op amps, with
subsequent savings in cost and power consumption. The transfer

Input resistance is high, thus permitting the signal source to
have an unbalanced output impedance.

Furthermore, the circuit gain may be fine trimmed using an
optional trim resistor, RG. Like the three op amp circuit, CMR
increases with gain, once initial trimming is accomplished—but
CMR is still dependent upon the ratio matching of Resistors R1
through R4. Resistor values for this circuit, using the optional
gain resistor, RG, can be calculated using
