MAX5415EUD
Dual, 256-Tap, Low-Drift, Digital Potentiometers in 14-Pin TSSOP
General DescriptionThe MAX5413/MAX5414/MAX5415 is a family of dual
linear taper digital potentiometers. Each device has two
3-terminal potentiometers. The MAX5413/MAX5414/
MAX5415 operate from +2.7V to +5.5V single-supply
voltages and use an ultra-low 0.1µA supply current.
These devices also provide glitchless switching
between resistor taps, as well as a convenient power-
on reset (POR) that sets the wiper to the midscale posi-
tion at power-up. Each potentiometer consists of a fixed
resistor with a wiper contact that is digitally controlled
through a 3-wire serial interface and has 256 tap points.
It performs the same function as a discrete potentiome-
ter or variable resistor.
These parts are ideal for applications requiring digitally
controlled resistors. Three resistance values are avail-
able: 10kΩ(MAX5413), 50kΩ(MAX5414), and 100kΩ
(MAX5415). A nominal resistor temperature coefficient
of 35ppm/°C end-to-end and 5ppm/°C ratiometric make
the MAX5413/MAX5414/MAX5415 ideal for applications
requiring low temperature-coefficient variable resistors,
such as adjustable-gain circuit configurations.
The MAX5413/MAX5414/MAX5415 are available in a 14-
pin TSSOP package. Each device is guaranteed over the
extended industrial temperature range (-40°C to +85°C).

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.

ELECTRICAL CHARACTERISTICS (continued)(VDD= +5V, unless otherwise noted. VH= VDD, VL= 0, TA= TMINto TMAX. Typical values are at VDD= +5V, TA= +25°C,
unless otherwise noted.)
Note 2:The DNL and INL are measured with the potentiometer configured as a voltage-divider with HX= VDDand LX= 0. The wiper
terminal is unloaded and measured with an ideal voltmeter.
Note 3:The DNL and INL are measured with the potentiometer configured as a variable resistor. HXis unconnected and LX= 0. At
VDD= +5V, the wiper terminal is driven with a source current of 400µA for the 10kΩconfiguration, 80µA for the 50kΩconfig-
uration, and 40µA for the 100kΩconfiguration. At VDD= +3V, 200µA/40µA/20µA for 10kΩ/50kΩ/100kΩconfigurations,
respectively.
Note 4:The wiper resistance is the worst value measured by injecting into WX, a current IW= VDD/ RHL.
Note 5:Digital timing is guaranteed by design.
