NOTES
1VDL is the maximum differential input voltage at G = 1 for specified nonlinearity, V DL at other gains = 10 V/G. VD = actual differential input voltage.
1Example: G = 10, VD = 0.50. VCM = 12 V – (10/2 × 0.50 V) = 9.5 V.
Specifications subject to change without notice.
Specifications shown in boldface are tested on all production unit 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.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
