Product details

16-bit precision DAC in a compact 8-pin MSOP

The Maxim MAX5443AEUA+ is a 16-bit, single-channel, voltage-output digital-to-analog converter built on an R-2R ladder architecture. It delivers a settling time of 1µs typical.

What the 1µs settling and ±0.5 LSB mean for your BOM

A 1µs typical settling time to 16-bit accuracy means this DAC can update at roughly 1 MSPS in a single-shot or burst mode, assuming the SPI clock keeps up.

Package and footprint — fits tight analog front-ends

Active lifecycle — no obsolescence clock ticking

ROHS3 compliant. For a procurement decision, this means no last-time-buy pressure and no forced redesign window. If you are reviewing a BOM for long-life industrial or instrumentation equipment, this DAC does not introduce supply-chain risk from a pending discontinuation.

Frequently asked questions

What is MAX5443AEUA+'s listed output type?

The output type is voltage - unbuffered. This means the DAC output is the raw R-2R ladder voltage without an internal output buffer amplifier. The output impedance is determined by the R-2R network (typically 5-20 kΩ), so the load should be high-impedance or buffered externally.
