The 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 simple 3-wire up/down interface allows manual switching or high speed digital control. The AD5227 presets to midscale at power-up. When CS is enabled, the devices changes step at every clock pulse. The direction is determined by the state of the U/D pin (see Table 1). The interface is simple to activate by any host controller, discrete logic, or manually with a rotary encoder or pushbuttons. The AD5227's 64-step resolution, small footprint, and simple interface enable it to replace mechanical potentiometers and trimmers with typically 6x improved resolution, solid-state reliability, and design layout flexibility, resulting in a considerable cost savings in end users' systems.
