General Description
The MAX5494–MAX5499 10-bit (1024-tap), dual, non-
volatile, linear-taper, programmable voltage-dividers
and variable resistors perform the function of a
mechanical potentiometer, but replace the mechanics
with a 3-wire SPI-compatible serial interface. The
MAX5494/MAX5495 are dual, 3-terminal, programma-
ble voltage-dividers; the MAX5496/MAX5497 are dual,
2-terminal variable resistors; and the MAX5498/
MAX5499 include one 2-terminal variable resistor and
one 3-terminal programmable voltage-divider.
The MAX5494–MAX5499 feature an internal, nonvolatile,
electrically erasable programmable read-only memory
(EEPROM) that stores the wiper position for initialization
during power-up. The 3-wire SPI-compatible serial inter-
face allows communication at data rates up to 7MHz.
The MAX5494–MAX5499 are ideal for applications requir-
ing digitally controlled potentiometers. End-to-end resis-
tance values of 10k and 50k are available with a
35ppm/°C end-to-end temperature coefficient. The ratio-
metric temperature coefficient is 5ppm/°C for each chan-
nel, making these devices ideal for applications requiring
low-temperature-coefficient programmable voltage-
dividers such as low-drift, programmable-gain amplifiers.
The MAX5494–MAX5499 operate with either a single
power supply (+2.7V to +5.25V) or dual power supplies
(±2.5V). The devices consume 400A (max) of supply
current when writing data to the nonvolatile memory
and 1.5A (max) of standby supply current. The
devices are available in space-saving (5mm x 5mm x
0.8mm), 16-pin TQFN package and are specified over
the extended (-40°C to +85°C) temperature range.
