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 potentiometers 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 interface can be disabled to prevent unwanted adjustment. The MAX5527/MAX5528/MAX5529 provide an end-to-end resistance of 100k, 50k, and 10k, 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, 0.25A (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 MAX packages. Each device is guaranteed over the -40C to +105C temperature range.
