AD524集成電路（IC）的數(shù)字電位計(jì)規(guī)格書PDF中文資料

AD524屬于集成電路（IC）的數(shù)字電位計(jì)。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD524數(shù)字電位計(jì)數(shù)字電位器是一系列集成電路器件，可提供類似于傳統(tǒng)機(jī)械電位器或變阻器的可調(diào)節(jié)電阻，但通過電子信號而非機(jī)械輸入來進(jìn)行控制。雖然這些器件的電阻可耗散的電能相對有限，但其電子控制能力有助于小型化、自動化和遠(yuǎn)程控制信號級模擬電路，而這些電路本來可能會使用機(jī)械電位器。

GENERAL DESCRIPTION

The AD8428 is an ultralow noise instrumentation amplifier designed to accurately measure tiny, high speed signals. It delivers industry-leading gain accuracy, noise, and bandwidth.

All gain setting resistors for the AD8428 are internal to the part and are precisely matched. Care is taken in both the chip pinout and layout. This results in excellent gain drift and quick settling to the final gain value after the part is powered on.

The high CMRR of the AD8428 prevents unwanted signals from corrupting the signal of interest. The pinout of the AD8428 is designed to avoid parasitic capacitance mismatches that can degrade CMRR at high frequencies.
