TEMPERATURE RANGE Rated −25 +85 −25 +85 −55 +125 °C Storage −65 +150 −65 +150 −65 +150 °C 1 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 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. 2 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 the incremental gain (VY + VZ) VX. 3 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.
