Each of the two independent pots is 10k end-to-end, controlled via a three-wire Up/Down interface (U/D, INC, CS). The wiper position is volatile — it defaults to midscale on power-up — so this part is suited for adjustable gain, offset trim, or volume control where the setting is re-established each power cycle, not for storing calibration constants across power loss. ## Key ratings and what they mean for the BOM Wiper resistance is 225 ohms typical. Temperature coefficient is 35ppm/°C. The Up/Down interface uses three GPIOs (U/D, INC, CS) — not I2C or SPI. That means any microcontroller with free digital pins can drive it, but verify your MCU has the headroom; no dedicated serial peripheral is needed. ## Lifecycle and sourcing The MAX5451EUD+ is listed as Active (current production) and ROHS3 compliant. No end-of-life notice or last-time-buy risk for new designs.","metaTitle":"MAX5451EUD+ Digital Potentiometer, 10k, 256 Taps, Linear","metaDescription":"MAX5451EUD+ dual 10k digital pot with 256 taps, linear taper, Up/Down interface, 2.7V-5.5V supply, -40°C to 85°C.
