The MAX5417/MAX5418/MAX5419 nonvolatile, linear-

taper, digital potentiometers perform the function of a

mechanical potentiometer, but replace the mechanics

with a simple 2-wire digital interface, allowing communi-

cation with multiple devices. 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 fast-mode I

face allows communication at data rates up to 400kbps,

minimizing board space and reducing interconnection

complexity in many applications. Each device is available

with one of four factory-preset addresses (see the

Selector Guide) and features an address input for a total

of eight unique address combinations.

The MAX5417/MAX5418/MAX5419 provide three nomi-

nal resistance values: 50kΩ (MAX5417), 100kΩ

(MAX5418), or 200kΩ (MAX5419). The nominal resistor

temperature coefficient is 50ppm/°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 MAX5417/MAX5418/MAX5419 are available in a

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

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