10kΩ digital pot with 100-tap resolution
The DS1804Z-010+ from Analog Devices is a single-channel digital potentiometer offering 10kΩ end-to-end resistance with 100 equally spaced taps (linear taper) and a non-volatile memory that retains the wiper position after power-off.
Up/Down interface and 8-SOIC package
The device uses a three-wire Up/Down interface (CS, INC, U/D) — a simple pulse-counting protocol that doesn't need an I²C or SPI bus, so it works with any microcontroller with spare GPIOs. Typical wiper resistance is 400Ω, which adds a small series offset but stays consistent across the tap range.
