ANALOG RESISTOR CHARACTERISTICS (-40 C to +85 C; V
CAPACITANCE
AC ELECTRICAL CHARACTERISTICS
NOTES:
1. All voltages are referenced to ground.
2. Resistor inputs cannot exceed the substrate bias voltage, Vb, in the negative direction.
3. Absolute linearity is used to determine wiper voltage versus expected voltage as determined by wiper
