AD5144A Datasheet Nonvolatile Digital Potentiometer

Manufacturer: Analog Devices

Overview: Data Sheet.

Download the AD5144A datasheet PDF. This datasheet also includes the AD5124 variant, as both parts are published together in a single manufacturer document.

General Description

The AD5124/AD5144/AD5144A potentiometers provide a nonvolatile solution for 128-/256-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the Ax, Bx, and Wx pins.

The low resistor tolerance and low nominal temperature coefficient simplify open-loop applications as well as applications requiring tolerance matching.

The linear gain setting mode allows independent programming of the resistance between the digital potentiometer terminals, through the RAW and RWB string resistors, allowing very accurate resistor matching.
