Product Introduction

Overview

The AD5204BRU10, manufactured by Analog Devices Inc., is a 4-channel digitally controlled variable resistor (VR) device. It is part of the AD5204/AD5206 series, which provides electronic adjustment functions similar to those of a potentiometer or variable resistor. 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. This device is designed for applications requiring precise and programmable resistance adjustments.
