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.","metaTitle":"MAX5403EUB+ Digital Potentiometer 10kΩ 256-Tap SPI 10-uMAX","metaDescription":"MAX5403EUB+ dual 10kΩ digital pot with 256 taps, SPI interface, linear taper. 2.7V-5.5V supply, -40°C to +85°C.
