DESCRIPTION

· The MAX5432–MAX5435 are nonvolatile, linear-taper digital potentiometers with a 2-wire serial interface, replacing mechanical potentiometers.
· They feature 32 tap points and internal EEPROM for wiper position recall at power-up.
· Available in 50kΩ and 100kΩ resistance values, with low temperature coefficients ideal for precision applications.
· Operates with a fast-mode I2C-compatible serial interface up to 400kbps.
· Offered in 3mm x 3mm 8-pin TDFN and 6-pin thin SOT23 packages, suitable for extended temperature ranges (-40°C to +85°C).

FEATURES

· Compact 3mm x 3mm 8-Pin TDFN and 6-Pin Thin SOT23 packages.
· Power-on recall of wiper position from nonvolatile memory.
· Low temperature coefficients: 35ppm/°C end-to-end and 5ppm/°C ratiometric.
· Resistance options: 50kΩ and 100kΩ.
· Fast 400kbps I2C-compatible serial interface.
· Low static supply current: 500nA typical.
· Single-supply operation from +2.7V to +5.25V.
· 32 tap positions with high accuracy: ±0.15 LSB INL and DNL typical.

APPLICATIONS

· Replacement for mechanical potentiometers.
