For higher temperatures, the current doubles every 10°C. 3Matching is defined as the difference between parameters of the two amplifiers. 4Defined as voltage between inputs, such that neither exceeds ±10 V from ground. 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. Specifications subject to change without notice.
