Specifications tested using +10 V output unless otherwise indicated. 2Gain and balance adjustments guaranteed capable of trimming output voltage error and symmetry error to zero. 3Test Condition: +V S = +18 V, –VS = –18 V; +VS = +13.5 V, VS = –13 .5 V. 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. Specifications subject to change without notice.
