End-to-end resistance is 10 kOhm with a linear taper. That gives you about 39 Ohm per step — fine enough to set a voltage divider ratio or trim a reference without external resistors. It talks over SPI — three wires (CS, SCK, DIN) plus the wiper output. No address lines because it is a single device, so the bus master just clocks in a 8-bit word to set the wiper position. The wiper resistance is 275 Ohm typical, which matters if you are sourcing current into a low-impedance load. Temperature coefficient is 35 ppm/°C typical — the resistance drifts about 0.35 Ohm per degree, negligible for most trim jobs. ## Industrial temp, small package — field-swap friendly The 8-TSSOP/MSOP package (0.118-inch body width) is small enough for tight layouts, and the 8-uMAX/uSOP supplier package is the same footprint — one PCB layout serves both. Surface-mount, so it goes through reflow; no hand-soldering needed unless you are doing a quick swap in the field with a hot-air station. Memory type is volatile — the wiper position resets to mid-scale on power-up. If you need the setting to survive a power cycle, you will need to store the value in an external EEPROM or MCU flash and reload it at boot. ## Active production, no end-of-life notice Tolerance is ±25% on the end-to-end resistance. That is typical for digital pots — the absolute resistance value is loose, but the ratiometric accuracy between taps is tight. If you need a precise divider ratio, this part delivers; if you need a specific 10 kOhm ±1%, look elsewhere.","metaTitle":"MAX5402EUA+ 10k SPI Digital Pot, 256 Taps, Linear Taper","metaDescription":"Analog Devices MAX5402EUA+ digital potentiometer: 10kOhm, 256 taps, SPI, linear taper, 2.7-5.5V, -40 to 85°C.
