Application Scenarios & Design Considerations

Single Digitally-Controlled (XDCP) Potentiometer

Alternative Part Number

  • DS1803Z-010 --: Dual digital potentiometer with I2C interface, functionally similar to the X9271 single/dual digital pot and widely available.
  • AD5241BRZ10 --: I2C-compatible digital potentiometer with comparable 10k ohm resistance and nonvolatile wiper setting, suitable replacement.
  • MCP4011-103E/SN --: Low-cost single digital potentiometer with similar resolution and serial control, good drop-in option for many X9271 applications.
  • AD5272BRMZ-20 --: Single-channel I2C digital potentiometer with similar 20k ohm end-to-end resistance and nonvolatile memory, a well-established replacement for X9271-type digital pots.
  • MCP4551-103E/MS --: Single I2C digital potentiometer with 10k ohm resistance and volatile wiper, pin-compatible in function and widely available as an alternative to Xicor-style digital pots.
