NOTES
1
Gain Error and Gain TC are for the AD625 only. Resistor Network errors will add to the specified errors.
2
V
DL
is the maximum differential input voltage at G = 1 for specified nonlinearity. V
DL
at other gains = 10 V/G. V
D
= actual differential input voltage.
Example: G = 10, V
D
= 0.50; V
CM
= 12 V – (10/2 × 0.50 V) = 9.5 V.
Specifications subject to change without notice.
All min and max specifications are guaranteed. 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.
