AD8403 Datasheet PDF

●The AD8403ARZ10 is a quad-channel Digital Potentiometer performs the same electronic adjustment function as a mechanical potentiometer or variable resistor. Each part contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by the digital code loaded into the controlling serial input register. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. Unique switching circuit minimizes the high glitch inherent in traditional switched resistor designs, avoiding any make-before-break or break-before-make operation.

● <5µA Power shutdown

● 10MHz Update data loading rate

●ESD sensitive device. Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
