MAX5405EUB
Dual 256-Tap, Low-Drift, Digital Potentiometers in 10-レMAX
General DescriptionThe MAX5403/MAX5404/MAX5405 is a family of dual
linear taper digital potentiometers. Each device has one
3-terminal potentiometer and one 2-terminal variable
resistor (Figure 1). The MAX5403/MAX5404/MAX5405
operate from +2.7V to +5.5V single-supply voltages
and use an ultra-low supply current of 0.1µA. These
devices also provide glitchless switching between
resistors taps as well as a convenient power-on reset
(POR) that sets the wiper to the midscale position at
power-up. The 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 per-
forms the same function as a discrete potentiometer or
variable resistor.
These parts are ideal for applications requiring digitally
controlled resistors. Three resistance values are avail-
able: 10kΩ(MAX5403), 50kΩ(MAX5404), and 100kΩ
(MAX5405). A nominal resistor-temperature coefficient
of 35ppm/°C end-to-end and 5ppm/°C ratiometric make
the MAX5403/MAX5404/MAX5405 ideal for applications
requiring low temperature-coefficient variable resistors,
such as adjustable-gain circuit configurations.
The MAX5403/MAX5404/MAX5405 are available in a 10-
pin µMAX package. Each device is guaranteed over the
extended industrial temperature range (-40°C to +85°C).

unless otherwise noted.)
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.

unless otherwise noted.)
Note 1:Linearity is defined in terms of the HXto LXcode-dependent resistance.
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. For the 3-terminal potentiometer
(Pot A), HAis unconnected and LA= 0. For the 2-terminal potentiometer (Pot B), only LB= 0. At VDD= +5V, the wiper termi-
nal is driven with a source current of 400µA for the 10kΩconfiguration, 80µA for the 50kΩconfiguration, and 40µA for the
100kΩconfiguration. At VDD= +3V, 200µA/40µA/20µA for 10kΩ/50kΩ/100kΩconfiguration 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.
