Overview
The AD5206BRU100, 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. The AD5206BRU100 is available in a 24-lead TSSOP package and is guaranteed to operate over the extended industrial temperature range of −40°C to +85°C.
