Product details

Dual 10kΩ digital pot with 256 taps — what it is and where it fits

The MAX5403EUB+ is a dual-channel, 256-tap digital potentiometer in a 10-uMAX/uSOP package. Each channel presents a 10kΩ end-to-end resistance with a linear taper, controlled over an SPI interface.

Package and footprint

The 10-uMAX/uSOP package (3.00mm body width) is a common small-outline footprint. It is surface-mount, so a reflow profile is needed — no socket for field swaps. The SPI interface uses four pins (CS, SCK, SDI, and SDO for daisy-chain), leaving six pins for the two potentiometer channels and supply.

Lifecycle and sourcing

It is ROHS3 compliant. No last-time-buy or obsolescence risk for new designs.

Frequently asked questions

Is MAX5403EUB+ compatible with 3.3V logic?

Yes, the supply range of 2.7V to 5.5V includes 3.3V. The SPI logic thresholds scale with VDD, so at 3.3V supply, the digital inputs are 3.3V-compatible.

What applications use MAX5403EUB+?

Typical uses include programmable gain/offset adjustment on analog front-ends, LCD bias trimming, sensor calibration loops, and any application needing a digitally-set voltage divider or variable resistor in industrial or test equipment.

What is the closest pin-compatible alternative to MAX5403EUB+?

Within the same family, the MAX5402EUB+ is a single-channel version in the same 10-uMAX package. For a dual-channel part with the same pinout, the MAX5403EUB+ is the standard; no direct second-source is listed in the manufacturer's cross-reference.
