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 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
-40
°C to +105°C temperature range.
