AD5227BUJZ10-R2 Datasheet PDF - ADI

The AD5227BUJZ10-R2 is a 64-position up/down control Digital Potentiometer performs the same electronic adjustment function as a 5V potentiometer or variable resistor. It"s 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). The interface is simple to activate by any host controller, discreet 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.

● Simple up/down digital or manual configurable control

● Midscale preset

● Chip select enable multiple device operation

● 0.4µA Typical and 3µA maximum ultra-low power

● 1µs Fast adjustment time

●ESD sensitive device. Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
