AD5273 is a 64-position one-time programmable digital potentiometer, with low power consumption, fast settling time and wide operating voltage range.
The AD5273 digital potentiometer provides 64 programmable positions using fuse‑link OTP technology. It can be programmed via a 2‑wire I²C‑compatible interface and, once programmed, retains its setting permanently regardless of supply variations.
Designed for applications such as system calibrations, automotive electronics adjustments, and replacement of mechanical trimmers, the device is offered in 1 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ resistance options in a compact 8‑lead SOT‑23 package. It operates from 2.7 V to 5.5 V and supports a wide temperature range of –40 °C to +105 °C.
