Specifications subject to change without notice.
Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min
and max specifications are guaranteed, although only those shown in boldface are tested on all production units.
Over the 100 mV to 10 V operating range total error is the sum of a percent of reading term and an output offset. With this input dynamic range the input offset
The most accurate representation of total error with low level inputs is the summation of a percent of reading term, an output offset and an input offset multiplied by
When using supplies below 13 V, the 10 V reference pin must be connected to the 2 V pin in order for the AD538 to operate correctly.
contribution to total error is negligible compared to the percent of reading error. Thus, it is specified indirectly as a part of the percent of reading error.
