General Description
The MAX5417/MAX5418/MAX5419 nonvolatile, linear-
taper, digital potentiometers perform the function of a
mechanical potentiometer by replacing 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 I2C-compatible serial interface
allows communication at data rates up to 400kbps, mini-
mizing board space and reducing interconnection com-
plexity in many applications. Each device is available with
one of four factory-preset addresses (see the
Ordering
Information/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: 50k
(MAX5417), 100k
(MAX5418), or 200k
(MAX5419). 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 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.
