Product details

14-bit precision DAC with fast settling for industrial control loops

The Maxim MAX5544ESA+ is a 14-bit voltage-output digital-to-analog converter built around an R-2R ladder architecture. The unbuffered voltage output means the load impedance matters — plan for a downstream buffer if the DAC drives a low-impedance input or a long cable. Data transfer uses a standard SPI interface, which keeps the digital-side pin count low and lets the part talk to most microcontrollers without a glue-logic gate.

R-2R architecture and linearity — what the INL/DNL numbers mean

The integral nonlinearity is specified at ±4 LSB maximum, and the differential nonlinearity at ±0.5 LSB maximum. A DNL within ±0.5 LSB guarantees monotonicity.

Package and supply — layout constraints

The single 5 V supply rail for both analog and digital sections simplifies decoupling.

Frequently asked questions

Can MAX5544ESA+ be used with 3.3V logic?

The digital supply voltage is specified at 5 V, not 3.3 V. The SPI input thresholds are referenced to the 5 V digital supply rail, so direct connection to a 3.3 V microcontroller output may not meet the VIH minimum. Use a level translator or a 5 V-tolerant MCU SPI port if the digital supply is 5 V.

Is MAX5544ESA+ lead-free and RoHS compliant?

Yes, the part is ROHS3 compliant per the manufacturer's listing.

What are the equivalents or replacements for MAX5544ESA+?

The MAX5544ESA+ is an active part with no official replacement announced. For a pin-compatible alternative within the same function, look at other 14-bit voltage-output DACs in the 8-SOIC package from Maxim that use an SPI interface and a single 5 V supply — verify the settling time and linearity against your requirements before substituting.
