Application Scenarios & Design Considerations

Low Noise, Low Power, 32 Taps

Alternative Part Number

  • MCP4021-502E/SN --: Single digital potentiometer with 5k ohm resistance and SPI interface, functionally similar to the X9315 in a compact SOIC package.
  • AD5220BRM10 --: 10k ohm digital potentiometer with up/down interface, a common drop-in style alternative for X9315 series designs.
  • DS1804Z-010 --: Nonvolatile digital potentiometer with increment/decrement control, suitable replacement for X9315 applications.
  • ISL23315UFRUZ-T7A --: Renesas (successor to Intersil) single-channel 32-tap I2C digital potentiometer in the same 10k range, drop-in functional replacement with similar package and supply range.
  • AD5241BRUZ10 --: Single-channel 256-position I2C digital potentiometer with 10k resistance, comparable interface and supply voltage, suitable alternative from a different series.
  • MCP4018T-103E/OT --: Single 10k I2C digital potentiometer in a small SOT-23 package, low-cost alternative with similar I2C control interface for volume applications.
