MAX5488ETE
+2.7 V to +5.25 V, 10 Kom, dual, 256-tap, nonvolatile, SPI-interface, linear-taper digital potentiometer
General DescriptionThe MAX5487/MAX5488/MAX5489 dual, linear-taper,
digital potentiometers function as mechanical poten-
tiometers 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
50kΩand 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 a
16-pin 3mm x 3mm x 0.8mm thin QFN package. Each
device is guaranteed over the extended -40°C to +85°C
temperature range.

ABSOLUTE MAXIMUM RATINGSStresses 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= +25°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_ = VDDand 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 10kΩconfiguration, 80µA for the 50kΩconfiguration,
and 40µA for the 100kΩconfiguration. For VDD= +3V, the wiper terminal is driven with a source current of 200µA for the 10kΩ
configuration, 40µA for the 50kΩconfiguration, and 20µA for the 100kΩconfiguration.
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 Characteristicssection.
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 Characteristicssection).
Note 8:Digital timing is guaranteed by design and characterization, and is not production tested.
