All voltages are referenced to ground.
STBY
specified for V
CC
equal to 3.0V and 5.0V while control port logic pins are driven to V
CC
or GND.
Absolute linearity is used to determine wiper voltage versus expected voltage as determined by wiper position.
Relative linearity is used to determine the change of wiper voltage between two adjacent wiper positions.
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.
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.
Wiper load time is specified as the time required to load the wiper position stored in EEPROM once V
CC
has reached a
stable operating voltage greater than or equal to V
CC MIN
.
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 V
CC MIN
has been reached.
The maximum number of EEPROM write cycles is guaranteed by design and is not tested in production.
