The OPAx375 family incorporates internal electrostatic discharge (ESD) protection circuits on all pins, as shown

above. These ESD protection diodes also provide in-circuit, input overdrive protection, as long as the current is

limited to 10 mA as stated in the Absolute Maximum Ratings. Figure 83 shows how a series input resistor can be

added to the driven input to limit the input current. The added resistor contributes thermal noise at the amplifier

input and its value should be kept to a minimum in noise-sensitive applications.

8.3.6 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 the input offset voltage of an amplifier.

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 84. Ideal Gaussian Distribution

Figure 84 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).
