AD5165集成电路（IC）的数字电位计规格书PDF中文资料

AD5165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AD5165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 OVERVIEW

The AD5165 provides a compact 2.9 mm × 2.8 mm packaged solution for 256-position adjustment applications. These devices perform the same electronic adjustment function as mechanical potentiometers or variable resistors, with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance. The AD5165’s supply voltage requirement is 2.7 V to 5.5 V, but its logic voltage requirement is 1.8 V to VDD. The AD5165 consumes very low quiescent power during standby mode and is ideal for battery-operated applications.
