NOTES

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.

for further information.

±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.

Ω 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.
