Figure 27. 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,

Figure 28. 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
impedance is reduced to insignificance by the high open-loop
gain of the OP77.
