ELECTRICAL CHARACTERISTICS (continued)
(V DD = +5V, V REF = +10V, V OUT1 = V OUT2 = 0V, Circuit of Figure 1, T A = T MIN to T MAX , unless otherwise noted.)
Note 1: Gain error is measured using internal feedback resistor. Full-scale range (FSR) = V REF .
Note 2: Gain TempCo measured from +25°C to T MAX and from +25°C to T MIN .
Note 3: Guaranteed by design.
