Specifications subject to change without notice. Specifications shown in boldface are tested on all devices at final electrical test at TMIN, 25 °C, and T MAX. 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. AD674B/AD774B–SPECIFICATIONS (T MIN to TMAX with VCC = +15 V 10% or +12 V 5%, VLOGIC = +5 V 10%, VEE = –15 V 10% or –12 V 5%, unless otherwise noted.) REV. C –2– |
