NOTES
1The AD570 is a selected version of the AD571 10-bit A-to-D converter. Only TTL logic inputs should be connected to Pins 1 and 18 (or no connection made) or
damage may result.
2For details on grade package offerings for SD-grade in accorance with MIL-STD-883, refer to Analog Devices’ Military Products databook or current /883 data sheet.
Specifications subject to change without notice.
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.
