AD5254 Datasheet (Analog Devices) - Quad 64-/256-Position I2C Nonvolatile Memory Digital Potentiometers

AD5254, Quad 64-/256-Position I2C Nonvolatile Memory Digital Potentiometers

The AD5253/AD52541 are quad-channel, I2C, nonvolatile memory, digitally controlled potentiometers with 64/256 positions, respectively.

These devices perform the same electronic adjustment functions as mechanical potentiometers, trimmers, and variable resistors.
