Figure 7. Precision High-Gain Differential Amplifier
The high gain, gain linearity, CMRR, and low TCVos of the
OP77 make it possible to obtain performance not previously
available in single-stage very high-gain amplifier applications.
For best CMR,
R

must equal

. In this example,
with a 10 mV differential signal, the maximum errors are as listed
in Table I.

Figure 8. Isolating Large Capacitive Loads
This circuit reduces maximum slew-rate but allows driving
capacitive loads of any size without instability. Because the boon
resistor is inside the feedback loop, its effect on output imped-
ance is reduced to insignificance by the high open-loop gain
of the OP77.
