9 / 16 page X9241 9 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 (VH – VL)/63, single pot (4) Max. = all four arrays cascaded together, Typical = individual array resolutions. ABSOLUTE MAXIMUM RATINGS* Temperature under Bias .................. –65 °C to +135°C Storage Temperature ....................... –65 °C to +150°C Voltage on SCK, SCL or any Address Input with Respect to VSS ................................... –1V to +7V Voltage on any VH or VL Referenced to VSS ......... ±8V ∆V = |VH–VL|......................................................... 16V Lead Temperature (Soldering, 10 seconds) ...... 300 °C *COMMENT Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and the 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 condi- tions for extended periods may affect device reliability. RECOMMENDED OPERATING CONDITIONS Temperature Min. Max.
