It includes the effects of internal voltage reference, gain and offset errors. 8Full-Scale TC = ∆FS/∆T, where ∆FS is the full-scale change from T A = 25 °C to T MIN or TMAX. 9Guaranteed by design and characterization, not production tested. 100 V to 10 V output range is available only when V DD ≥ +14.25 V.
