The AD5263 is a four-channel digital potentiometer from Analog Devices with a rated voltage of 15V, 256 positions, and SPI or I2C interface selectable via AD0 and AD1 pins.
The AD5263 digital potentiometer provides four independent channels, each offering 256 programmable resistance steps. It features pin‑selectable SPI‑compatible 3‑wire or I²C‑compatible 2‑wire interfaces, power‑on preset to midscale, and optional programmable logic outputs for driving external loads.
Designed for automotive and industrial environments, the device operates from a single 4.5 V‑15 V supply or dual ±5 V supplies, and is supplied in a 24‑lead TSSOP package. Applications include mechanical potentiometer replacement, audio level control, sensor calibration, and programmable filters.
