PRECISION HIGH GAIN DIFFERENTIAL AMPLIFIER
The high gain, gain linearity, CMRR, and low TCVOS of the
OP177 make it possible to obtain performance not previously
available in single stage, very high gain amplifier applications.
For best CMR,
R2
R1 must equal
R4
R3
In this example, with a 10 mV differential signal, the maximum
errors are listed in Table 6.

ISOLATING LARGE CAPACITIVE LOADS
The circuit shown in Figure 29 reduces maximum slew rate but
allows driving capacitive loads of any size without instability.
Because the 100 Ωresistor is inside the feedback loop, its effect
on output impedance is reduced to insignificance by the high
open loop gain of the OP177.

PRECISION ABSOLUTE VALUE AMPLIFIER
The high gain and low TCVOS assure accurate operation with
inputs from microvolts to volts. In this circuit, the signal always
appears as a common-mode signal to the op amps (for details,
see Figure 31).
