NOTES
1
The data output lines have active pull-ups to source 0.5 mA. The
DATA READY
line is open collector with a nominal 6 kΩ internal pull-up resistor.
2
For details on grade and package offerings for SD-grade in accordance with MIL-STD-883, refer to Analog Devices’ Military Products databook or current /883B
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.
