AD5111BCPZ10-RL7集成电路（IC）的数字电位计规格书PDF中文资料

AD5111BCPZ10-RL7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AD5111BCPZ10-RL7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 AD5111/AD5113/AD5115 provide a nonvolatile solution for 128-/64-/32-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8 and up to ±6 mA current density in the A, B, and W pins. The low resistor tolerance, low nominal temperature coefficient, and high bandwidth simplify open-loop applications, as well as tolerance matching applications.
