64-Tap, One-Time Programmable, Linear-Taper Digital Potentiometers
General Description
The MAX5527/MAX5528/MAX5529 linear-taper digital
potentiometers perform the same function as mechanical
potentiometers, replacing the mechanics with a simple
2-wire up/down digital interface. These digital poten-
tiometers provide an optional one-time programmable
feature that sets the power-on reset position of the wiper.
Once the wiper position is programmed, the 2-wire inter-
face can be disabled to prevent unwanted adjustment.
The MAX5527/MAX5528/MAX5529 provide an end-to-end
resistance of 100kΩ, 50kΩ, and 10kΩ, respectively. The
devices feature low temperature coefficients of 35ppm/°C
end-to-end and 5ppm/°C ratiometric. All devices offer 64
wiper positions and operate from a single +2.7V to +5.5V
supply. An ultra-low, 0.25µA (typ) standby supply current
saves power in battery-operated applications.
The MAX5527/MAX5528/MAX5529 are available in
3mm x 3mm, 8-pin TDFN and 5mm x 3mm, 8-pin
µMAX®packages. Each device is guaranteed over the
-40°C to +105°C temperature range.

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:All devices are production tested at TA = +25°C, and are guaranteed by design for TA= -40°C to +105°C.
Note 2:The wiper resistance is measured by driving the wiper terminal with a source of 20µA for the MAX5527, 40µA for the
MAX5528, and 200µA for the MAX5529.
Note 3:Wiper at midscale with a 10pF load.
Note 4:Digital timing is guaranteed by design, not production tested.
Note 5:Wiper setting time is measured for a single step from U/Dtransition until wiper voltage reaches 90% of final value.
Note 6:Power-up time is the period of time from when the power supply is applied, until the serial interface is ready for writing.
