Overview
The AD5206BRZ10-REEL is a 6-channel, 256-position digitally controlled variable resistor (VR) device produced by Analog Devices Inc. This device performs the same electronic adjustment function as a potentiometer or variable resistor, making it an ideal replacement for mechanical potentiometers. Each channel contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the SPI-compatible serial-input register.
