General Description
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: 50k
Ω (MAX5422), 100kΩ
(MAX5423), or 200k
Ω (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.
