AD526集成电路（IC）的数字电位计规格书PDF中文资料

AD526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AD526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 AD8253 is an instrumentation amplifier with digitally programmable gains that has GΩ input impedance, low output noise, and low distortion making it suitable for interfacing with sensors and driving high sample rate analog-to-digital converters (ADCs). It has high bandwidth of 10 MHz, low THD and fast settling time of 615 ns to 0.001. Offset drift and gain drift are

specified to 1.2 μV/°C and 10 ppm/°C, respectively for G = 1000. In addition to its wide input common voltage range, it boasts a high common-mode rejection of 80 dB at G = 1 from dc to

50 kHz. The combination of precision dc performance coupled with high speed capabilities make the AD8253 an excellent candidate for data acquisition. Furthermore, this monolithic solution simplifies design and manufacturing, and boosts performance of instrumentation by maintaining a tight match of internal resistors and amplifiers.
