NOTES:
1. All Voltages are referenced to ground.
2. Typical Values are for T
3. Resistors input voltages cannot go below V
4. Maximum current specifications are based on the clock rate of
5. The DS1666 is available in three end-to-end resistor values. These include 10K
6. Absolute tolerance is used to compare measured wiper voltage versus expected wiper voltage as
7. -3dB cutoff frequency characteristics for the DS1666 depend on potentiometer total resistance. The
