PIN DESCRIPTIONS
VCC - Power Supply. The DS1666 will support supply voltages ranging from +4.5 to +5.5 volts.
GND -
Ground Terminal.
VB - Negative Bias. The DS1666 will support a negative bias ranging from 0 to -5 volts.
H -
High-Terminal of Potentiometer. It is not required that this terminal be connected to a potential
greater than the VL terminal. Voltage applied to the VH terminal can not exceed the power-supply
voltage, (VCC), or go below the negative bias, (VB).
VL - Low-Terminal of Potentiometer. It is not required that this terminal be connected to a potential less
than the VH terminal. Voltage applied to the VL terminal cannot exceed the power-supply voltage, (VCC),
or go below the negative bias (VB).
VW - Wiper of the Potentiometer. Its position on the resistor array is controlled by the 3-terminal control
port. Voltage applied to the wiper cannot exceed the power-supply voltage, VCC, or go below the
negative bias (VB).
CS
-
Chip Select. The CS input is used to activate the control port of the DS1666. This input is active
low. When in a high-state, activity on the INC and U/ D port pins will not affect or change wiper
position.
INC
-
Wiper Movement Control. This input provides for wiper position changes when the CS pin is low.
Wiper position changes will occur one position per high-to-low transition of this input signal. Position
changes will not occur if the CS pin is in a high-state.
U/ D -
Up/Down Control. This input sets the direction of wiper movement. When in a high-state and CS
is low, any high-to-low transition on INC will cause a one position movement of the wiper towards the
VH terminal. When in a low-state and CS is low, any high-to-low transitions on INC will cause the
position of the wiper to move towards the VL terminal.
