Description Power Supply Ground

¯¯¯¯¯ Control Input. With CS¯¯ low, a low-to-high transition Up/Down

increments or decrements the wiper position.

¯¯ transition determines the Chip Select Input. A high-to-low CS

¯ is high, or decrement if U/D¯ is low. mode: increment if U/D

Notes:

(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability. (2) Derate 3.1mW/ºC above TA = +70ºC
