Overview
The AD5260BRUZ20, produced by Analog Devices Inc., is a 1-channel, 256-position, SPI interface digitally controlled variable resistor (VR) device. This component operates from either a single +5 V to +15 V supply or a dual ±5 V supply, allowing for terminal voltage adjustment within these supply voltages. It is designed to perform the same electronic adjustment function as a potentiometer or variable resistor, offering solid-state reliability and compact electronic packaging. The AD5260BRUZ20 is available in a thin 1.1 mm height TSSOP 14-lead surface mount package.
