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 (V_H - V_L)/63, single pot
4. Typical = Individual array resolution.
5. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
6. Limits should be considered typical and are not production tested.
7. This parameter is not production tested. Parameter established by characterization.
Power-up Requirements
(Power-up sequencing can affect correct recall of the wiper
registers) The preferred power-on sequence is as follows:
First V_CC and then the potentiometer pins, R_H, R_L, and R_W.
Voltage should not be applied to the potentiometer pins
before V_CC is applied. The V_CC ramp rate specification
should be met, and any glitches or slope changes in the V_CC
line should be held to <100mV if possible. Also, V_CC should
not reverse polarity by more than 0.5V. Recall of wiper
position will not be complete until V_CC reaches its final
value.
