COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; functional operation of the
device (at these or any other conditions above those
listed in the operational sections of this specification) is
not implied. Exposure to absolute maximum rating con-
ditions for extended periods may affect device reliability.

25°C, each pot
V+ = 5V, V- = -5V, I_W = 3mA
V+ = 2.7V, V- = -2.7V, I_W = 1mA

V_{w(n + 1)} - [V_{w(n) + MI}]
Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
(2) Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a
potentiometer. It is a measure of the error in step size.
(3) MI = RTOT/63 or (R_H - R_L)/63, single pot (=LSB)
