You can use this chart to calculate approximate probability of a specification in a unit; for example, for TLV930x,

the typical input voltage offset is 500 µV, so 68.2% of all TLV930x devices are expected to have an offset from

–500 µV to +500 µV. At 4 σ (±2000 µV), 99.9937% of the distribution has an offset voltage less than ±2000 µV,

which means 0.0063% of the population is outside of these limits, which corresponds to about 1 in 15,873 units.

Specifications with a value in the minimum or maximum column are assured by TI, and units outside these limits

will be removed from production material. For example, the TLV930x family has a maximum offset voltage of 2.5

mV at 125°C, and even though this corresponds to 5 σ (≈1 in 1.7 million units), which is extremely unlikely, TI

assures that any unit with larger offset than 2.5 mV will be removed from production material.

For specifications with no value in the minimum or maximum column, consider selecting a sigma value of

sufficient guardband for your application, and design worst-case conditions using this value. For example, the 6σ

value corresponds to about 1 in 500 million units, which is an extremely unlikely chance, and could be an option

as a wide guardband to design a system around. In this case, the TLV930x family does not have a maximum or

minimum for offset voltage drift, but based on Figure 6-2 and the typical value of 2 µV/°C in Section 6.7, it can be

calculated that the 6-σ value for offset voltage drift is about 12 µV/°C. When designing for worst-case system

conditions, this value can be used to estimate the worst possible offset across temperature without having an

actual minimum or maximum value.

However, process variation and adjustments over time can shift typical means and standard deviations, and

unless there is a value in the minimum or maximum specification column, TI cannot assure the performance of a

device. This information should be used only to estimate the performance of a device.

7.4 Device Functional Modes

The TLV930x has a single functional mode and is operational when the power-supply voltage is greater than 4.5

V (±2.25 V). The maximum power supply voltage for the TLV930x is 40 V (±20 V).
