It packs four independent DACs into a single 14-TDFN (3x3 mm) package, controlled over an I²C bus. The architecture is built for trimming or margining power supplies, biasing laser diodes, or setting current levels in industrial transmitters where a voltage-output DAC would need an extra op-amp stage. Each channel sinks or sources current directly, so the output is unbuffered — the load sees the DAC's own output impedance. That matters when the load impedance varies: the current accuracy holds as long as the compliance voltage stays within the supply rails. The I²C interface handles all four channels on a single bus address, with the data word setting the output current magnitude. ## Key ratings and what they mean for the BOM Integral nonlinearity is ±1 LSB maximum, differential nonlinearity ±0.5 LSB maximum — monotonicity is guaranteed, so the output never reverses direction as the code increments. That is the spec that matters when the DAC is in a closed-loop control path: a non-monotonic step can cause oscillation. ## Where it fits — typical applications and environments This class of current-output DAC is common in power-supply margining (adjusting a DC-DC converter's feedback node up or down during test), laser-diode bias control in fiber-optic transceivers, and programmable current-loop transmitters. The I²C interface makes it a natural fit for systems that already have an I²C bus — microcontrollers, FPGAs, or dedicated PMBus controllers. The 14-TDFN package is small enough for space-constrained designs like SFP modules or compact sensor heads. ## Sourcing and lifecycle — active, no LTB risk The DS4424N+ carries an active lifecycle status from Maxim (now part of Analog Devices). ROHS3 compliant, so it passes the current EU material-restriction requirements without an exemption.","metaTitle":"Maxim DS4424N+ 7-Bit Current-Output DAC, I²C, 14-TDFN","metaDescription":"Maxim DS4424N+ 7-bit current-output DAC with I²C interface, 4 channels, current sink/source architecture.

The four channels and I²C interface suit designs that need multiple adjustable current sinks or sources on a single bus address."},{"question":"What package does the DS4424N+ come in?","answer":"It is supplied in a 14-WFDFN with exposed pad, designated as 14-TDFN (3x3 mm) by Maxim. The shipping medium is Tube. Surface-mount only."},{"question":"What is the output type of the DS4424N+?","answer":"Current - Unbuffered. The DAC output is a current sink or current source directly from the internal current-steering architecture — no internal buffer amplifier. The load sees the DAC's output impedance, so compliance voltage must stay within the supply rails."},{"question":"Is there a pin-compatible equivalent or replacement for the DS4424N+?","answer":"No pin-compatible equivalent is listed in the available sourcing records. The DS4424N+ uses a unique 14-TDFN pinout specific to Maxim's current-output DAC family. For a functional replacement with the same I²C interface and current-sink/source architecture, evaluate the DS4422 or DS4424 variants — but verify the pinout and package match your layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS4424N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS4424N when reusing this data.
