Overview
The AD8403ARZ10-REEL is a quad-channel, 256-position digitally controlled variable resistor (VR) device produced by Analog Devices Inc. This component performs the same electronic adjustment function as a mechanical potentiometer or variable resistor. It is part of the AD8400/AD8402/AD8403 family, which offers single, dual, or quad-channel configurations. The AD8403 specifically contains four independent variable resistors and is available in 24-lead PDIP, SOIC, and TSSOP packages. Each variable resistor offers a completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper, controlled by a digital code loaded into the serial input register.
