Dual, 256-Tap, Nonvolatile, SPI-Interface, Linear-Taper Digital Potentiometers
General Description
The MAX5487/MAX5488/MAX5489 dual, linear-taper,
digital potentiometers function as mechanical potentiometers
with a simple 3-wire SPI™-compatible digital interface
that programs the wipers to any one of 256 tap positions.
These digital potentiometers feature a nonvolatile memory
(EEPROM) to return the wipers to their previously stored
positions upon power-up.
The MAX5487 has an end-to-end resistance of 10kΩ,
while the MAX5488 and MAX5489 have resistances of
50kΩ and 100kΩ, respectively. These devices have a low
35ppm/°C end-to-end temperature coefficient, and operate
from a single +2.7V to +5.25V supply.
The MAX5487/MAX5488/MAX5489 are available in
16-pin 3mm x 3mm x 0.8mm TQFN or 14-pin TSSOP
packages. Each device is guaranteed over the extended
-40°C to +85°C temperature range.

DC Electrical Characteristics
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 1: All devices are production tested at TA = +85°C and are guaranteed by design and characterization for -40°C < TA <
+85°C.Note 2: DNL and INL are measured with the potentiometer configured as a voltage-divider with H_ = VDD and L_ = 0. The wiper
terminal is unloaded and measured with an ideal voltmeter.Note 3: DNL and INL are measured with the potentiometer configured as a variable resistor. H_ is unconnected and L_ = 0. For
VDD = +5V, the wiper terminal is driven with a source current of 400µA for the 10kΩ configuration, 80µA for the 50kΩ
configuration, and 40µA for the 100kΩ configuration. For VDD = +3V, the wiper terminal is driven with a source current of
200µA for the 10kΩ configuration, 40µA for the 50kΩ configuration, and 20µA for the 100kΩ configuration.Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 3 into W_ with L_ = GND. RW =
(VW - VH) / IW.Note 5: The device draws higher supply current when the digital inputs are driven with voltages between (VDD - 0.5V) and (GND +
0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics section.Note 6: Wiper at midscale with a 10pF load.Note 7: Wiper-settling time is the worst-case 0-to-50% rise time, measured between tap 0 and tap 127. H_ = VDD, L_ = GND, and
the wiper terminal is unloaded and measured with a 10pF oscilloscope probe (see Tap-to-Tap Switching Transient in the
Typical Operating Characteristics section).Note 8: Digital timing is guaranteed by design and characterization, and is not production tested.
(VDD = +2.7V to +5.25V, VH = VDD, VL = GND, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VDD = +5.0V,
