Temperature under bias........................ –65 to +135°C  
Storage temperature............................. –65 to +150°C  
Voltage on SCK, SCL or any address input  
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  
conditions for extended periods may affect device  
reliability.

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 potenti-  
ometer. It is a measure of the error in step size.  
(3) MI = RTOT/255 or (V /R –V /R )/255, single pot
