Single-Supply, Low Power, Precision FET Input Quad Buffer

GENERAL DESCRIPTION The AD8244 is a precision, low power, FET input, quad unity-gain buffer that is designed to isolate very large source impedances from the rest of the signal chain. The 2 pA maximum bias current, near zero current noise, and 10 T? input impedance introduce almost no error, ev

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(jì)用于將極高的源阻抗與信號(hào)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(jí)別，也幾乎不產(chǎn)生任何誤差。 \n\n 很多傳統(tǒng)運(yùn)算放大器都將電源引腳排列在同相輸入引腳旁邊。 保護(hù)走線必須從這些引腳之間穿過(guò)，以避免漏電流遠(yuǎn)大于FET輸入運(yùn)算放大器的偏置電流。在DIP乃至SOIC等大型封裝內(nèi)，保護(hù)走線可以在引腳間穿過(guò)；但是，很多現(xiàn)代應(yīng)用不允許這些封裝消耗過(guò)多的面積。 AD8244具有獨(dú)特的引腳排列可以解決這個(gè)問(wèn)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?
