Application Scenarios & Design Considerations

Quad Digitally Controlled Potentiometers

Alternative Part Number

  • AD5246BRJZ10 --: Single-channel I2C digital potentiometer with similar 10k ohm resistance and volatile wiper memory, suitable replacement for the X9409 in many applications.
  • MCP4017T-103E/LT --: I2C single digital potentiometer with 10k ohm end-to-end resistance and low voltage operation, offering comparable functionality in a smaller package.
  • DS1803Z-010 --: Dual I2C digital potentiometer with 10k ohm resistance and 2.7V operation, closely matching the X9409's dual-channel architecture and supply range.
  • ISL22346WFV14Z --: Quad digitally controlled potentiometer with I2C interface and non-volatile memory, functionally similar to the X9409 quad pot; Renesas/Intersil is the successor brand for Xicor parts.
  • AD5235BRUZ25 --: Dual-channel non-volatile digital potentiometer with SPI interface; a well-supported alternative when a quad pot is not strictly required, offering comparable resolution and memory retention.
  • MCP4641-502E/ST --: Dual I2C digital potentiometer with non-volatile wiper memory in a small package; widely available and suitable as a functional substitute for low-voltage digital pot applications.
  • ISL22326WFRU10Z --: Renesas/Intersil took over Xicor's digital potentiometer line; this is a dual 10k I2C non-volatile DCP in TSSOP-24, functionally equivalent to the X9409WV24I-2.7.
  • AD5252BRUZ10 --: Dual-channel 10k I2C non-volatile digital potentiometer in TSSOP-24, a close functional match with similar resolution and interface.
  • MCP4652-103E/ST --: Dual 10k I2C digital potentiometer in TSSOP-14, a viable alternative when board space allows re-layout; widely available and cost-effective.
