The AD5260BRUZ50-REEL7 is a single-channel, 256-tap digital potentiometer from Analog Devices with a 50 kΩ end-to-end resistance and a linear taper characteristic.
Interface and control
Programming is via a 3-wire SPI-compatible serial interface, with a cascade pin that allows daisy-chaining multiple devices on the same bus without additional GPIO. The wiper setting is volatile — it defaults to midscale on power-up and is lost when supply is removed. Resistance tolerance is ±30%, and the wiper resistance is 60 Ω typical, which sets the minimum end-to-end resistance floor in the lowest tap position.
The 0.65 mm lead pitch and standard TSSOP-14 footprint are compatible with common PCB layout rules; no exposed pad or thermal management is required for the 50 kΩ element at rated supply voltages.
Lifecycle and compliance
The part is ROHS3 compliant and carries the standard Analog Devices green marking.
