ABSOLUTE MAXIMUM RATINGS
RECOMMENDED OPERATING CONDITIONS
POTENTIOMETER CHARACTERISTICS
(Over recommended operating conditions unless otherwise stated.)
Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
(2) The minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to –2.0V for periods of less than 20ns. Maximum DC
(3) Latch-up protection is provided for stresses up to 100mA on address and data pins from –1V to V
(4) This parameter is tested initially and after a design or process change that affects the parameter.
(5) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a potentiometer.
(6) Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentio-
