NOTES
1
For 16-bit resolution, 1 LSB = 0.0015% of FSR = 15 ppm of FSR. For 15-bit resolution, 1 LSB = 0.003% of FSR = 30 ppm of FSR. For 14-bit resolution
1 LSB = 0.006% of FSR = 60 ppm of FSR. FSR stands for Full-Scale Range and is 10 V for a 0 V to + 10 V span and 20 V for a –10 V to +10 V span.
2
Gain error and gain drift measured using the internal reference. Gain drift is primarily reference related. See the Using the AD669 with the AD688 Reference section
for further information.
3
External current is defined as the current available in addition to that supplied to REF IN and SPAN/BIPOLAR OFFSET on the AD669.
4
Operation on
±
12 V supplies is possible using an external reference like the AD586 and reducing the output range. Refer to the Internal/External Reference Use section.
5
Measured with fixed 50
resistors. Eliminating these resistors increases the gain error by 0.25% of FSR (Unipolar mode) or 0.50% of FSR (Bipolar mode). Refer to
the Analog Circuit Connections section.
*Same as AD669AN/AR specification.
Specifications subject to change without notice.
Specifications 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 specifica-
tions are guaranteed. Those shown in boldface are tested on all production units.
