MAX5422/MAX5423/MAX5424

The MAX5422/MAX5423/MAX5424 nonvolatile, linear-

taper, digital potentiometers perform the function of a

mechanical potentiometer, but replace the mechanics

with a simple 3-wire SPI™-compatible digital interface.

Each device performs the same function as a discrete

potentiometer or variable resistor and has 256 tap points.

The devices feature an internal, nonvolatile EEPROM

used to store the wiper position for initialization during

power-up. The 3-wire SPI-compatible serial interface

allows communication at data rates up to 5MHz, mini-

mizing board space and reducing interconnection com-

plexity in many applications.

The MAX5422/MAX5423/MAX5424 provide three nomi-

nal resistance values: 50kΩ (MAX5422), 100kΩ

(MAX5423), or 200kΩ (MAX5424). The nominal resistor

temperature coefficient is 35ppm/°C end-to-end and

only 5ppm/°C ratiometric. This makes the devices ideal

for applications requiring a low-temperature-coefficient

variable resistor, such as low-drift, programmable gain-

amplifier circuit configurations.

The MAX5422/MAX5423/MAX5424 are available in a

3mm x 3mm 8-pin TDFN package, and are specified

over the extended -40°C to +85°C temperature range.
