1
Figures given are percent of full-scale, ±10 V (that is, 0.01% = 1 mV).
2
Can be reduced to 3 V using an external resistor between –V
S
and SF.
3
Irreducible component due to nonlinearity: excludes effect of offsets.
4
Using an external resistor adjusted to give a value of SF = 3 V.
5
See the functional block diagram (Figure 1) for definition of sections.
