It stores the wiper position in on-chip EEPROM, so the setting survives power cycles — no re-calibration after a brownout or field power-down. The 2.7V to 5.5V supply range lets it run off a 3.3V or 5V rail without a separate regulator. Typical applications include gain/offset trim in industrial sensors, LCD bias adjustment, and programmable voltage references in factory automation or outdoor telecom gear where the -40°C to 85°C temperature range is needed. ## 100 taps and linear taper — what that means for your adjustment range With 100 tap positions and a linear taper, each step changes the resistance by about 500Ω nominal (50kΩ / 100). The wiper resistance is 400Ω typical, which matters at the low end of the range: the first few taps will show a floor of about 400Ω plus the tap resistance, so don't expect a true zero-ohm wiper-to-B connection. ## Package and field-swap reality It comes in an 8-uMAX/uSOP package (3.00mm body width, 0.118\" pitch) — small enough for dense boards, but the lead pitch is still hand-solderable with a fine-tip iron and a loupe. No hot-air station required if you're careful. Orientation is marked by pin 1 dot on the package top; the 8-TSSOP alternate footprint is the same, so the part fits either land pattern. ## Lifecycle and sourcing — still active, no LTB clock ticking That means you can qualify it into a new BOM without worrying about a discontinuation window closing next quarter.","metaTitle":"DS1804U-050+T&R Digital Potentiometer, 50kΩ 100-Tap Linear","metaDescription":"DS1804U-050+T&R non-volatile digital pot, 50kΩ resistance, 100 taps, linear taper, 2.7V–5.5V supply, -40°C to 85°C, 8-uMAX package.
