AD5143BCPZ100-RL7

AD5143 is a potentiometer that provide a non-volatile solution for 256-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and upto ±6mA 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. The high bandwidth and low total harmonic distortion (THD) ensure optimal performance for ac signals, making the devices suitable for filter design. It is used in applications such as portable electronics level adjustment, LCD panel brightness and contrast controls, programmable filters, delays, and time constants, programmable power supplies etc.
