EVAL-AD5116EBZ

Single-Channel, 64Position, Push Button, ±8% Resistor Tolerance, Nonvolatile Digital Potentiometer

GENERAL DESCRIPTION

The AD5116 provides a nonvolatile digital potentiometer solution for 64-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the A, B, and W pins. The low resistor tolerance, low nominal temperature coefficient, and high bandwidth simplify open-loop applications, as well as tolerance matching applications.
