NOTES
1The AD558 S & T grades are available processed and screened lo MIL-STD-883 Class B. Consult Analog Devices’ Military Databook for details.
2Relative Accuracy is defined as the deviation of the code transition points from the ideal transfer point on a straight line from the offset to the full scale of the device.
See “Measuring Offset Error”.
3Operation of the 0 volt to 10 volt output range requires a minimum supply voltage of +11.4 volts.
4Passive pull-down resistance is 2 kΩ for 2.56 volt range, 10 kΩ for 10 volt range.
5Settling time is specified for a positive-going full-scale step to ± 1/2 LSB. Negative-going steps to zero are slower, but can be improved with an external pull-down.
6The full range output voltage for the 2.56 range is 2.55 V and is guaranteed with a +5 V supply, for the 10 V range, it is 9.960 V guaranteed with a +15 V supply.
7A monotonic converter has a maximum differential linearity error of ± 1 LSB.
8See Figure 7.
Specifications shown in boldface are tested on all production units at final electrical test.
Specifications subject to change without notice.
