Description
- Product Details
- 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 ). 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 6× improved resolution, solid-state reliability, and design layout flexibility, resulting in a considerable cost savings in end users’ systems.
- The AD5227 is available in a compact thin SOT-23-8 (TSOT-8) Pb-free package. The part is guaranteed to operate over the automotive temperature range of −40°C to +105°C.
- Users who consider EEMEM potentiometers should refer to some recommendations in the Applications section.
- **Applications**
- * Mechanical potentiometer and trimmer replacements
- * LCD backlight, contrast, and brightness controls
- * Portable electronics level adjustment
- * Programmable power supply
- * Digital trimmer replacements
- * Automatic closed-loop control
- 1RWA increments if RWB decrements and vice versa.
