The AD5273 is a 64-position OTP digital potentiometer featuring ultralow power, fast settling time, and a wide temperature range.
The AD5273 is a 64‑position, one‑time programmable (OTP) digital potentiometer that uses fuse‑link technology to permanently set resistance values. It offers a low‑power operation (5 pA max) and a wide temperature range, making it suitable for system calibrations, electronic level settings, and automotive electronics adjustments.
The device is programmed via a 2‑wire I²C‑compatible digital interface and includes validation bits to confirm successful OTP programming. An evaluation kit and Windows‑based programming software are available for factory programming applications.
