The CS pin is the chip select input. Forcing the CS pin
to V
can increment and decrement the wiper. Depending on
the command, the wiper may (or may not) be saved to
non-volatile memeory (EEPROM). Forcing the CS pin
to V
These commands can increment and decrement the
wiper and enable or disable the WiperLock technology.
The wiper is saved to non-volatile memory (EEPROM).
The CS pin has an internal pull-up resistor. The resistor
will become “disabled” when the voltage on the CS pin
is below the V
is “floating”, the CS pin will be pulled to the V
(serial communication (the U/D pin) is ignored). And
when the CS pin is driven low (V

consumption when serial commands are occurring.

The U/D pin input is used to increment or decrement
the wiper on the digital potentiometer. An increment
moves the wiper one step toward terminal A, while a
decrement moves the wiper one step toward
terminal B.
