7.3.8 Overload Recovery
Overload recovery is defined as the time required for the op amp output to recover from a saturated state to a
linear state. The output devices of the op amp enter a saturation region when the output voltage exceeds the
rated operating voltage, either due to the high input voltage or the high gain. After the device enters the
saturation region, the charge carriers in the output devices require time to return back to the linear state. After
the charge carriers return back to the linear state, the device begins to slew at the specified slew rate. Thus, the
propagation delay in case of an overload condition is the sum of the overload recovery time and the slew time.
The overload recovery time for the OPAx991 is approximately 500 ns.
7.3.9 Typical Specifications and Distributions
Designers often have questions about a typical specification of an amplifier in order to design a more robust
circuit. Due to natural variation in process technology and manufacturing procedures, every specification of an
amplifier will exhibit some amount of deviation from the ideal value, like an amplifier's input offset voltage. These
deviations often follow Gaussian ("bell curve"), or normal distributions, and circuit designers can leverage this
information to guardband their system, even when there is not a minimum or maximum specification in the
Electrical Characteristics table.
Figure 52. Ideal Gaussian Distribution
Figure 52 shows an example distribution, where µ, or mu, is the mean of the distribution, and where σ, or sigma,
is the standard deviation of a system. For a specification that exhibits this kind of distribution, approximately two-
thirds (68.26%) of all units can be expected to have a value within one standard deviation, or one sigma, of the
mean (from µ–σ to µ+σ).
Depending on the specification, values listed in the typical column of the Electrical Characteristics table are
represented in different ways. As a general rule of thumb, if a specification naturally has a nonzero mean (for
example, like gain bandwidth), then the typical value is equal to the mean (µ). However, if a specification
naturally has a mean near zero (like input offset voltage), then the typical value is equal to the mean plus one
standard deviation (µ + σ) in order to most accurately represent the typical value.
You can use this chart to calculate approximate probability of a specification in a unit; for example, for OPAx991,
the typical input voltage offset is 125 µV, so 68.2% of all OPAx991 devices are expected to have an offset from
–125 µV to 125 µV. At 4 σ (±500 µV), 99.9937% of the distribution has an offset voltage less than ±500 µV,
which means 0.0063% of the population is outside of these limits, which corresponds to about 1 in 15,873 units.
