Results from those tests are used to calculate outgoing quality levels. 3 Can be reduced down to 3 V using external resistor between –VS and SF. 4 Irreducible component due to nonlinearity; excludes effect of offsets. 5 Using external resistor adjusted to give SF = 3 V. 6 See Figure 1 for definition of sections.
