Application Scenarios & Design Considerations

Quad 16-/14-/12-Bit Rail-to-Rail DACs with I2C Interface

Alternative Part Number

  • AD5664BRMZ --: Quad 16-bit DAC with similar SPI interface and resolution, from the same parent company as Linear Technology, suitable drop-in functional replacement.
  • MCP4728A0-E/UN --: Quad 12-bit I2C DAC offering comparable multi-channel DAC functionality in a small package, good alternative when lower resolution is acceptable.
  • DAC8565IPW --: Quad 16-bit voltage-output DAC with SPI interface, similar channel count and resolution, widely available alternative from a different vendor.
  • AD5662BRMZ-1 --: Single-channel 16-bit DAC with internal reference and SPI interface, functionally similar to the LTC2619-1 and pin-compatible in many designs.
  • MCP4921-E/SN --: Single-channel 12-bit DAC with SPI interface in SOIC package, a lower-resolution but widely available and cost-effective substitute.
  • DAC8551IDGK --: 16-bit single-channel voltage-output DAC with SPI interface, comparable resolution and performance for similar applications.
