General Description
The MAX5432–MAX5435 nonvolatile, linear-taper, digi-
tal potentiometers perform the function of a mechanical
potentiometer, but replace the mechanics with a simple
2-wire serial interface. Each device performs the same
function as a discrete potentiometer or a variable resis-
tor and has 32 tap points.
The MAX5432–MAX5435 feature an internal, nonvolatile,
electrically erasable programmable read-only memory
(EEPROM) that returns the wiper to its previously stored
position at power-up. The fast-mode I
2
C-compatible
serial interface allows communication at data rates up to
400kbps, minimizing board space and reducing inter-
connection complexity. Each device is available with
multiple factory-preset I
2
C addresses (see the
Ordering
Information/Selector Guide).
Use the MAX5432–MAX5435 in applications requiring
digitally controlled resistors. Two resistance values are
available (50kΩ and 100kΩ) in a voltage-divider or vari-
able resistor configuration. The nominal resistor temper-
ature coefficient is 35ppm/°C end-to-end, and only
5ppm/°C ratiometric, making the devices ideal for
applications requiring a low-temperature-coefficient
variable resistor such as low-drift, programmable-gain
amplifier circuit configurations.
The MAX5432/MAX5433 are available in a 3mm x 3mm
8-pin TDFN package and the MAX5434/MAX5435 are
available in a 6-pin thin SOT23 package. The MAX5432–
MAX5435 are specified over the extended (-40°C to
+85°C) temperature range.
