AD5228 - 32-Position Manual Up/Down Control Potentiometer

Datasheet Summary

Description

The AD5228 is Analog Devices’ latest 32-step-up/step-down control digital potentiometer emulating mechanical potentiometer operation1.

Its simple up/down control interface allows manual control with just two external pushbutton tactile switches.

Features

  • 32-position digital potentiometer 10 kΩ, 50 kΩ, 100 kΩ end-to-end terminal resistance Simple manual up/down control Self-contained, requires only 2 pushbutton tactile switches Built-in adaptive debouncer Discrete step-up/step-down control Autoscan up/down control with 4 steps per second Pin-selectable zero-scale/midscale preset Low potentiometer mode tempco, 5 ppm/°C Low rheostat mode tempco, 35 ppm/°C Digital control compatible Ultralow power, IDD = 0.4 µA typ and 3 µA max Low operating voltage.
