SPECIFICATIONS
VS = ±15 V @ TA = 25°C, unless otherwise noted. Specifications 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.
