POWER SUPPLY Operating Range VCC 12 32 V Quiescent Current 4.2 5.5 mA Quiescent Current (External VLL) 3 mA TEMPERATURE RANGE Specified Performance −40 +85 °C 1 External capacitor selection must be as described in Figure 6. 2 Total Output Error includes Offset and Gain Error. Total Output Error and Offset Error are with respect to the Full-Scale Output and are measured with an ideal +5 V reference. If the internal reference is used, the reference errors must be added to the Offset and Total Output Errors. 3 PSRR is measured by varying VCC from 12 V to its maximum 32 V. Rev.
