Description
Push-Up Pin.
Connect to the external pushbutton. Active low. A 100 kΩ pull-up resistor is connected to V
Push-Down Pin.
Connect to the external pushbutton. Active low. A 100 kΩ pull-up resistor is connected to V
Resistor Terminal A. GND ≤V
Common Ground.
Wiper Terminal W. GND ≤ V
Resistor Terminal B. GND ≤ V
Power-On Preset. Output = midscale if PRE = GND; output = zero scale if PRE = V
No pull-up resistor is needed.
Positive Power Supply, 2.7 V to 5.5 V.
