AD5162 is a dual 256-position SPI digital potentiometer from Analog Devices. It features a small size (MSOP-10 package, 3mm x 4.9mm), wide operating temperature range (-40°C ~ +125°C), low power consumption (IDD = 6µA max), and low temperature drift (35 ppm/°C). It can be used for system calibration, electronic level setting, mechanical potentiometer replacement, permanent factory PCB setting, pressure sensor, temperature sensor, position sensor, chemical sensor, optical sensor, RF amplifier biasing, automotive electronics adjustment, etc.
The AD5162 is a dual‑channel digital potentiometer offering 256 positions per channel, selectable end‑to‑end resistance values (2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ) and a compact MSOP‑10 (3 mm × 4.9 mm) package. It operates from a single 2.7 V‑5.5 V supply and draws less than 6 µA, making it suitable for portable applications.
The datasheet provides detailed electrical characteristics, timing specifications for the 3‑wire SPI interface, absolute maximum ratings, pin descriptions, typical performance curves, and ordering information. An evaluation board and programming software are also described.
