NOTES
1_{Specified and tested over an input range of ±5 V.}
2_{Maximum current the AD684 can source (or sink). Testing guarantees that the accuracy of the held signal remains within 2.5 mV of its initial value.}
3_{The output is protected for a short circuit to common, VCC and VEE .}
4_{VCC and VEE at nominal voltage levels.}
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.
