Application Scenarios & Design Considerations

Quad, 8-Bit DAC with Rail-to-Rail Outputs

Alternative Part Number

  • AD7224KNZ --: Quad 8-bit voltage-output DAC with similar architecture and pinout, widely available and often used as a drop-in replacement in legacy Maxim designs.
  • LTC1257CN8 --: Single 12-bit voltage-output DAC in DIP package with comparable resolution and interface, suitable for designs needing higher precision than the MAX505.
  • DAC08EQ --: Classic 8-bit multiplying DAC in DIP package with similar functionality and long-term availability, useful as a functional substitute where exact pin compatibility is not critical.
