NOTES:
1. All voltages are referenced to ground.
2. Resistor inputs cannot exceed the substrate bias voltage, V
3. Capacitance values apply at 25 C.
4. Absolute linearity is used to determine wiper voltage versus expected voltage as determined by wiper
5. Relative linearity is used to determine the change in voltage between successive tap positions. Test
