AD5227 is Analog Devices latest 64-Step Up/Down Control Digital Potentiometer¹. This device performs the same electronic adjustment function as a 5 V potentiometer or variable resistor. Its common 3-wire up/down interface allows high-speed as well as low-speed digital controls. AD5227 presets to mid-scale in power up. When CS is enabled, the Up/Down direction is depended on the state of U/D and it executes at every clock pulse.

The interface is simple that can be controlled by any host controllers, discrete logics, and manually with rotary encoder or push buttons. AD5227 adequate resolution, small footprint, and simple interface enable it to be the potential replacements of mechanical potentiometers and trimmers with typically 6X improved resolution, solid-state reliability, and design layout flexibility. These enhancements can result in considerable cost saving in end users’ systems.

The AD5227 is available in compact thin SOT23-8 package. All parts are guaranteed to operate over the extended industrial temperature range of -40°C to +125°C.

Applications

Mechanical Potentiometers and Trimmers Replacements

LCD Contrast, Brightness, and Backlight Controls
