32-Tap, Nonvolatile, I C, Linear, Digital

Potentiometers

General Description

Features

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.

♦ Tiny 3mm x 3mm 8-Pin TDFN and 6-Pin Thin

SOT23 Packages

♦ Power-On Recall of Wiper Position from

Nonvolatile Memory

♦ 35ppm/°C End-to-End Resistance Temperature

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 I²C-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 I²C addresses (see the Ordering

Information/Selector Guide).

Coefficient

♦ 5ppm/°C Ratiometric Temperature Coefficient

♦ 50kΩ/100kΩ Resistor Values

♦ Fast 400kbps I²C-Compatible Serial Interface

♦ 500nA (typ) Static Supply Current

♦ +2.7V to +5.25V Single-Supply Operation

♦ 32 Tap Positions

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.

TOP VIEW

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.
