7.3.4 Typical Specifications and Distributions

Designers often have questions about a typical specification of an amplifier when designing a more robust

circuit. Because of natural variation in process technology and manufacturing procedures, every specification

of an amplifier exhibits some amount of deviation from the ideal value. The offset voltage of an amplifier is

one such example. These deviations often follow Gaussian (bell curve), or normal distributions. Thus, allowing

circuit designers to leverage this information to guard band the system, even when a minimum or maximum

specification is not in the Electrical Characteristics table.

Figure 7-4 shows an example distribution. In this figure, µ (or mu), is the mean of the distribution, and σ (or

sigma), is the standard deviation of a system. For specifications exhibiting this kind of distribution, approximately

two-thirds (68.26%) of all units are expected to have a value within one standard deviation of the mean. One

standard deviation of the mean is µ – σ to µ + σ.
