Overview
The AD5206BRUZ100, produced by Analog Devices Inc., is a 6-channel, 256-position digitally controlled variable resistor (VR) device. This component performs the same electronic adjustment function as a potentiometer or variable resistor, making it ideal for applications requiring precise and programmable resistance control. 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.
