Description
Positive Power Supply. Decouple this pin with 0.1 µF ceramic capacitors and 10 µF capacitors.
Terminal A of RDAC. GND ≤ V
Wiper Terminal of RDAC. GND ≤ V
Terminal B of RDAC. GND ≤ V
Ground Pin, Logic Ground Reference.
Clock Input. Each clock pulse executes the step-up or step-down of the resistance. The direction is determined
by the state of the U/D pin. CLK is a negative edge trigger. Data can be transferred at rates up to 50 MHz.
Up/Down Selection Counter Control.
Chip Select. Active Low.
Exposed Pad. The exposed pad is internally floating.
