AC TIMING Figure 4
NOTES:
1. All Voltages are referenced to ground.
2. Typical Values are for T
A
=25°C and nominal supply voltages.
3. Resistors input voltages cannot go below V
B
or exceed V
CC
by the amounts shown.
4. Maximum current specifications are based on the clock rate of INC input. This specification
represents the current required when changing the wiper position.
5. The DS1666 is available in three end-to-end resistor values. These include 10KΩ for the DS1666-10;
50KΩ for the DS1666-50; and 100KΩ for the DS1666-100.
6. Absolute tolerance is used to compare measured wiper voltage versus expected wiper voltage as
determined by wiper position.
7. -3dB cutoff frequency characteristics for the DS1666 depend on potentiometer total resistance. The
DS1666-10 is 1 MHz; the DS1666-50 is 200 KHz; and the DS1666-100 is 100 KHz.
8. Valid at 25°C only
