POWER-UP TIMING
Power-up Requirements
(Power-up sequencing can affect correct recall of the wiper
registers) The preferred power-on sequence is as follows:
First VCC and then the potentiometer pins, RH, RL, and RW.
Voltage should not be applied to the potentiometer pins
before VCC is applied. The VCC ramp rate specification
should be met, and any glitches or slope changes in the VCC
line should be held to <100mV if possible. Also, VCC should
not reverse polarity by more than 0.5V. Recall of wiper
position will not be complete until VCC reaches its final
value.

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. 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.
