Figure 54. Test Circuit for Overload Recovery Time
Figure 18 shows the positive overload recovery time of the
OP1177. The output recovers in less than 4 μs after being
overdriven by more than 100%.
The negative overload recovery of the OP1177 is 1.4 μs, as seen
THD + NOISE
The OPx177 has very low total harmonic distortion. This indicates
excellent gain linearity and makes the OPx177 a great choice for
high closed-loop gain precision circuits.
Figure 55 shows that the OPx177 has approximately 0.00025%
distortion in unity gain, the worst-case configuration for distortion.

CAPACITIVE LOAD DRIVE
OPx177 is inherently stable at all gains and capable of driving
large capacitive loads without oscillation. With no external
compensation, the OPx177 safely drives capacitive loads up to
1000 pF in any configuration. As with virtually any amplifier,
driving larger capacitive loads in unity gain requires additional
circuitry to assure stability.
In this case, a snubber network is used to prevent oscillation
and reduce the amount of overshoot. A significant advantage of
this method is that it does not reduce the output swing because
the Resistor RS is not inside the feedback loop.
Figure 56 is a scope shot of the output of the OPx177 in response
to a 400 mV pulse. The load capacitance is 2 nF. The circuit is
configured in positive unity gain, the worst-case condition for
stability.
As shown in Figure 58, placing an R-C network parallel to the
load capacitance (CL) allows the amplifier to drive higher values
of CL without causing oscillation or excessive overshoot.
There is no ringing, and overshoot is reduced from 27% to 5%
using the snubber network.
Optimum values for RS and CS are tabulated in Table 5 for several
capacitive loads, up to 200 nF. Values for other capacitive loads can
be determined experimentally.
