EVALUATION KIT AVAILABLE One-Time Programmable, Linear-Taper Digital Potentiometers MAX5527/MAX5528/MAX5529 General Description Features
The MAX5527/MAX5528/MAX5529 linear-taper digital o
Wiper Position Stored After One-Time Fuse
potentiometers perform the same function as mechanical
Programming
potentiometers, replacing the mechanics with a simple o
64 Tap Positions
2-wire up/down digital interface. These digital poten- o
Wiper Position Programmed Through Simple
tiometers provide an optional one-time programmable
2-Wire Up/Down Interface
feature that sets the power-on reset position of the wiper. Once the wiper position is programmed, the 2-wire inter- o
35ppm/°C End-to-End Temperature Coefficient
face can be disabled to prevent unwanted adjustment. o
5ppm/°C Ratiometric Temperature Coefficient
The MAX5527/MAX5528/MAX5529 provide an end-to-end o
Ultra-Low 1.5µA (max) Static Supply Current
resistance of 100kΩ, 50kΩ, and 10kΩ, respectively. The o
+2.7V to +5.5V Single-Supply Operation
devices feature low temperature coefficients of 35ppm/°C o
10kΩ, 50kΩ, and 100kΩ End-to-End Resistances
end-to-end and 5ppm/°C ratiometric. All devices offer 64 wiper positions and operate from a single +2.7V to +5.5V o
