19-3511; Rev 3; 11/07 EVALUATION KIT AVAILABLE 32-Tap, Nonvolatile, I2C, Linear, Digital Potentiometers MAX5432­MAX5435 General Description Features The MAX5432­MAX5435 nonvolatile, linear-taper, digi- Tiny 3mm x 3mm 8-Pin TDFN and 6-Pin Thin tal potentiometers perform the function of a mechanical SOT23 Packages potentiometer, but replace the mechanics with a simple2-wire serial interface. Each device performs the same Power-On Recall of Wiper Position from function as a discrete potentiometer or a variable resis- Nonvolatile Memory tor and has 32 tap points. 35ppm/°C End-to-End Resistance Temperature The MAX5432­MAX5435 feature an internal, nonvolatile, Coefficient electrically erasable programmable read-only memory(EEPROM) that returns the wiper to its previously stored 5ppm/°C Ratiometric Temperature Coefficient position at power-up. The fast-mode I2C-compatible 50k/100k Resistor Values serial interface allows communication at data rates up to400kbps, minimizing board space and reducing inter- Fast 400kbps I2C-Compatible Serial Interface connection complexity. Each device is available with 500nA (typ) Static Supply Current multiple factory-preset I2C addresses (see the OrderingInformation/Selector Guide). +2.7V to +5.25V Single-Supply Operation Use the MAX5432­MAX5435 in applications requiring 32 Tap Positions digitally controlled resistors. Two resistance values are ±0.15 LSB INL (typ), ±0.15 LSB DNL (typ) available (50k and 100k) in a voltage-divider or vari-able resistor configuration. The nominal resistor temper-ature coefficient is 35ppm/°C end-to-end, and only5ppm/°C ratiometric, making the devices ideal for Pin Configurations applications requiring a low-temperature-coefficientvariable resistor such as low-drift, programmable-gain TOP VIEW amplifier circuit configurations. The MAX5432/MAX5433 are available in a 3mm x 3mm + + 8-pin TDFN package and the MAX5434/MAX5435 are H 1 8 W VDD 1 6 L available in a 6-pin thin SOT23 package. The MAX5432­ SDA 2 7 L GND 2 5 W
