• Manufacturer Part Number: cat5270
• Description: Dual Digitally Programmable Potentiometers Dpp With 256 Taps & I2c Compatible Interface
• Manufacturer: ON Semiconductor

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The minimum DC input voltage is −0.5 V. During transitions, inputs may undershoot to −2.0 V for periods of less than 20 ns. Maximum DC
2. Latch−up protection is provided for stresses up to 100 mA on address and data pins from −1 V to V
3. This parameter is tested initially and after a design or process change that affects the parameter.
4. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
5. Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentiometer.
