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 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.

  • Software Adjusts and Programs Wiper Position
  • Fully Assembled and Tested

Product Detail

The MAX5527 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that evaluates the digital potentiometer. Included software generates the required signals for one-time-programmable (OTP) operation and allows easy control of the wiper position. An on-board 8-pin µMAX® socket eases replacement of the device. The EV kit connects to a standard IBM-compatible PC parallel (printer) port.

Windows® 98/2000/XP-compatible software provides a user-friendly interface to exercise the MAX5527's features. The program is menu driven and offers a graphic user interface.

This EV kit can also be used to evaluate the MAX5528 and MAX5529 digital potentiometers.

Applications

  • Mechanical Potentiometer Replacements
  • Products Using One-Time Factory Calibration
