Overview
The AD5206BRZ100, produced by Analog Devices Inc., is a 6-channel, 256-position digitally controlled variable resistor (VR) device. This component is designed to perform the same electronic adjustment function as a mechanical potentiometer or variable resistor. It features multiple independently programmable channels, making it versatile for various applications. The device operates with a 3-wire SPI-compatible serial data input and supports both single-supply (+2.7 V to +5.5 V) and dual-supply (±2.7 V) operations. Each channel contains a fixed resistor with a wiper contact that can be programmed to tap the fixed resistor value at a specific point determined by a digital code loaded into the SPI-compatible serial-input register.
