AD5262BRU20-REEL7集成电路（IC）的数字电位计规格书PDF中文资料

AD5262BRU20-REEL7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AD5262BRU20-REEL7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 AD5260/AD5262 provide a single- or dual-channel, 256-position, digitally controlled variable resistor (VR) device.* These devices perform the same electronic adjustment function as a potentiometer or variable resistor. Each channel of the AD5260/AD5262 contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the SPI-compatible serial-input register.
