For higher temperatures, the current doublers every 10 °C. 3Matching is defined as ther difference between parameters of the two amplifiers. 4Defined as the maximum safe voltage between inputs, such that neither exceeds ± 10 V from ground. 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.
