AD5255 Datasheet (Analog Devices) - 3-Channel Digital Potentiometer with Nonvolatile Memory

AD5255, 3-Channel Digital Potentiometer with Nonvolatile Memory

The AD5255 provides dual 512-position and a single 128-position digitally controlled variable resistors1 (VR) in a TSSOP package.

This device performs the same electronic adjustment function as a potentiometer, trimmer, or variable resistor.

Each VR offers a completely programmable value of resistan
