Nonvolatile, 32-Position Digital Potentiometer

Note 1:
All voltages are referenced to ground.
Note 2:
STBY specified for VCC equal to 3.0V and 5.0V while control port logic pins are driven to VCC or GND.
Note 3:
Absolute linearity is used to determine wiper voltage versus expected voltage as determined by wiper position.
Note 4:
Relative linearity is used to determine the change of wiper voltage between two adjacent wiper positions.
Note 5:
The INC low to CS inactive time is the transition time that allows the three control pins to become inactive without writing
the wiper position to the EEPROM.
Note 6:
Wiper storage time is the time required for the wiper position to be written to the EEPROM. During this time, the three-ter-
minal interface is inactive.
Note 7:
Wiper load time is specified as the time required to load the wiper position stored in EEPROM once VCC has reached a
stable operating voltage greater than or equal to VCC MIN.
Note 8:
Power-up time is specified as the time required before the three control pins become active once a stable power supply
level of at least VCC MIN has been reached.
Note 9:
The maximum number of EEPROM write cycles is guaranteed by design and is not tested in production.
