The AD5260/AD5262 is a single/dual-channel 15V digital potentiometer with 256 positions that can perform the same electronic adjustment function as a potentiometer.
The AD5260 (single‑channel) and AD5262 (dual‑channel) provide digitally controlled variable resistors with 256 positions and linear resistance steps. They operate from a single 5 V to 15 V supply or from dual supplies (+5.5 V) and include a power‑on mid‑scale preset and an active‑low shutdown pin.
Typical applications include mechanical potentiometer replacement, audio level control, programmable voltage‑to‑current conversion, and instrumentation gain/offset adjustment. The devices support daisy‑chain operation via an open‑drain SDO pin and are offered in thin‑profile TSSOP‑14 (AD5260) and TSSOP‑16 (AD5262) packages.
