AD8244

單電源、低功耗、精密FET輸入四通道緩沖器

AD8244是一款精密、低功耗、FET輸入、四通道、單位增益緩沖器，設(shè)計用于將極高的源阻抗與信號鏈的其余部分相隔離。 其最大偏置電流為2 pA，電流噪聲接近于零，輸入阻抗則為10 TΩ，因此即使源阻抗為MΩ級別，也幾乎不產(chǎn)生任何誤差。 \n\n 很多傳統(tǒng)運算放大器都將電源引腳排列在同相輸入引腳旁邊。 保護走線必須從這些引腳之間穿過，以避免漏電流遠大于FET輸入運算放大器的偏置電流。在DIP乃至SOIC等大型封裝內(nèi)，保護走線可以在引腳間穿過；但是，很多現(xiàn)代應(yīng)用不允許這些封裝消耗過多的面積。 AD8244具有獨特的引腳排列可以解決這個問題，它在物理上將高阻抗輸入與低阻抗電源以及其它緩沖器; ? 低功耗\n250 μA（每放大器的最大電源電流） \n\n?
