GENERAL DESCRIPTION
The AD5122/AD5142 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 accurate resistor matching.
The high bandwidth and low total harmonic distortion (THD) ensure optimal performance for ac signals, making these devices suitable for filter design.
