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. 4PSRR is measured by varying V CC from 12 V to its maximum 32 V. Specifications subject to change without notice. |
