AD5273集成电路（IC）的数字电位计规格书PDF中文资料

AD5273属于集成电路（IC）的数字电位计。由亚德诺半导体技术有限公司制造生产的AD5273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。

GENERAL DESCRIPTION

The AD5273 is a 64-position, One-Time-Programmable (OTP) digital potentiometer4 that employs fuse link technology to achieve the permanent program setting. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors. It allows unlimited adjustments before permanently setting the resistance values. The AD5273 is programmed using a 2-wire, I2C compatible digital control. During the write mode, a fuse blow command is executed after the final value is determined, therefore freezing the wiper position at a given setting (analogous to placing epoxy on a mechanical trimmer).
