Maxim Integrated MAX5529GUA

Description
The MAX5527/MAX5528/MAX5529 linear-taper digital potentiometers replace mechanical potentiometers with a simple 2-wire up/down digital interface. They feature an optional one-time programmable feature that sets the power-on reset position of the wiper. Once programmed, the 2-wire interface can be disabled to prevent unwanted adjustment.
The devices provide end-to-end resistances of 100kΩ, 50kΩ, and 10kΩ, respectively. They have 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.
