General Description
The MAX5481–MAX5484 10-bit (1024-tap) nonvolatile,
linear-taper, programmable voltage-dividers and vari-
able resistors perform the function of a mechanical
potentiometer, but replace the mechanics with a pin-
configurable 3-wire serial SPI-compatible interface or
up/down digital interface. The MAX5481/MAX5482 are
3-terminal voltage-dividers and the MAX5483/MAX5484
are 2-terminal variable resistors.
The MAX5481–MAX5484 feature an internal, non-
volatile, electrically erasable programmable read-only
memory (EEPROM) that stores the wiper position for ini-
tialization during power-up. The 3-wire SPI-compatible
serial interface allows communication at data rates up
to 7MHz. A pin-selectable up/down digital interface is
also available.
The MAX5481–MAX5484 are ideal for applications
requiring digitally controlled potentiometers. Two end-to-
end resistance values are available (10k
and 50k
) in a
voltage-divider or a variable-resistor configuration (see
the
Selector Guide
). The nominal resistor temperature
coefficient is 35ppm/°C end-to-end, and only 5ppm/°C
ratiometric, making these devices ideal for applications
requiring low-temperature-coefficient voltage-dividers,
such as low-drift, programmable gain-amplifiers.
The MAX5481–MAX5484 operate with either a +2.7V to
+5.25V single power supply or ±2.5V dual power sup-
plies. These devices consume 400μA (max) of supply
current when writing data to the nonvolatile memory
and 1.0μA (max) of standby supply current. The
MAX5481–MAX5484 are available in a space-saving
(3mm x 3mm), 16-pin TQFN, or a 14-pin TSSOP pack-
age and are specified over the extended (-40°C to
+85°C) temperature range.
