GENERAL DESCRIPTION

The AD5203 provides a quad channel, 64-position digitallycontrolled variable resistor (VR) device. These parts perform the same electronic adjustment function as a potentiometer or variable resistor. The AD5203 contains four independent variable resistors in a 24-lead SOIC and the compact TSSOP-24 packages.

AD5203属于集成电路（IC） > 数字电位计。亚德诺半导体技术有限公司制造生产的AD5203数字电位计数字电位器是一系列集成电路器件，可提供类似于传统机械电位器或变阻器的可调节电阻，但通过电子信号而非机械输入来进行控制。虽然这些器件的电阻可耗散的电能相对有限，但其电子控制能力有助于小型化、自动化和远程控制信号级模拟电路，而这些电路本来可能会使用机械电位器。
