±15V, 128-Tap, Low-Drift Digital Potentiometers
General Description
The MAX5436–MAX5439 are 128-tap high-voltage (±5V
to ±15V) digital potentiometers in packages that are half
the size of comparable devices in 8-pin SO. They perform
the same function as mechanical potentiometers, but
replace the mechanics with a simple digital interface. The
digital logic is powered by a separate single +2.7V to
+5.25V supply voltage (VCC). The resistor string uses its
own analog supplies (VDDand VSS) that require
VDD- VSSto be greater than 9V and less than 31.5V. This
allows for greater flexibility in voltage ranges that can be
used with these devices. Examples of analog supply
ranges include not only dual voltages of ±5V to ±15V, but
single-supply voltages, such as +10V, +15V, +30V, -30V,
and more, as long as the ranges of VDD- VSSand VCC-
VSSare met.
The MAX5437/MAX5439 include an on-chip, high-
voltage, uncommitted amplifier, providing additional
reductions in board space and cost. Other features
include low 35ppm/°C end-to-end and 5ppm/°C ratio-
metric resistor temperature coefficients, a 3-wire SPI™/
QSPI™/MICROWIRE™-compatible serial interface, and
a power-on reset to midscale.
The MAX5436/MAX5438 are available in 10-pin µMAX
packages. The MAX5437/MAX5439 are available in 14-
pin TSSOP package. Each device is guaranteed over
the extended temperature range of -40°C to +85°C.

ABSOLUTE MAXIMUM RATINGS
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:The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VDDand L = VSS. The
wiper terminal is unloaded.
Note 2:The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = VSS.
The wiper terminal is driven with a source current of 80µA for the 50kΩconfiguration and 40µA for the 100kΩconfiguration.
Note 3:The wiper resistance is measured assuming the source currents given in Note 2.
Note 4:The device draws current in excess of the specified supply current when the digital inputs are driven with voltages between
(VCC- 0.5V) and (GND + 0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristicssection.
Note 5:Guaranteed by design and characterization.
