Analog Devices AD5243/AD5248 Digital Potentiometer Datasheet
The AD5243 and AD5248 provide compact 3 mm × 4.9 mm packaged dual 256‑position digital potentiometers. They operate from a single 2.7 V to 5.5 V supply, consume less than 6 pA on power‑on, and feature a low temperature coefficient of 35 ppm/°C. The devices support full read/write of the wiper register and include optional address decode pins on the AD5248 for multi‑device I²C buses.
Typical applications include system calibrations, sensor adjustments, RF amplifier biasing, automotive electronics tuning, and gain or offset control. An evaluation board and Windows‑based programming software are available to simplify factory programming and system integration.
