Product Summary

The AD8403ARZ10 is a Digital Potentiometer.It provides a single, dual or quad channel, 256 position digitally controlled variable resistor (VR) device. The AD8403ARZ10 performs the same electronic adjustment function as a potentiometer or variable resistor. The device contains four independent variable resistors in 24-lead PDIP, SOIC and TSSOP packages. The applications of the AD8403ARZ10 include: Mechanical Potentiometer Replacement, Programmable Filters, Delays, Time Constants, Volume Control, Panning, Line Impedance Matching, Power Supply Adjustment.
