Overview
The AD5262BRU200-REEL7 is a 2-channel, 256-position, digitally controlled variable resistor (VR) device produced by Analog Devices Inc. This component operates as a digital potentiometer, providing the same electronic adjustment function as a mechanical potentiometer or variable resistor. It is designed for applications requiring precise and programmable resistance settings, with each channel featuring a fixed resistor and a wiper contact that can be set to various positions based on a digital code loaded into the SPI-compatible serial-input register.
