APPLICATIONS
The high gain, gain linearity, CMRR, and low TCV
OP77 make it possible to obtain performance not previously
available in single-stage, very high-gain amplifier applications.
For best CMR,
10 mV differential signal, the maximum errors are as listed in
Table 7.

TCI
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.
