NOTES
1AD767 “S” specifications shown for information only. Consult Analog Devices Military Databook or contact factory for a controlled specification sheet.
2AD767A Chips specifications are tested at +25
°C and, when in boldface, at +85°C. They are typical at –25°C.
3The digital input specifications are 100% tested at +25
°C, and guaranteed but not tested over the full temperature range.
4Adjustable to zero.
5FSR means “Full-Scale Range” and is 20 V for
±10 V range and 10 V for the ±5 V range.
6A minimum power supply of
±12.5 V is required for a ±10 V full-scale output and ±11.4 V is required for all other voltage ranges.
Specifications subject to change without notice.
Specifications shown in boldface are tested on all production units at final electrical test (except per Notes 1 and 2). 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.
