精密、低噪聲、低輸入偏置電流運(yùn)算放大器（單通道）

OPx177系列由極高精度的單通道、雙通道和四通道放大器組成，具有極低失調(diào)電壓和漂移、低輸入偏置電流、低噪聲及低功耗等特性。使用1000 pF以上容性負(fù)載時(shí)輸出穩(wěn)定，無(wú)需外部補(bǔ)償。電源電壓為30 V時(shí)，每個(gè)放大器的電源電流小于500 μA。其內(nèi)置500 Ω串聯(lián)電阻可以保護(hù)輸入信號(hào)，允許輸入信號(hào)電平高出電源電壓若干伏特，并保證無(wú)反相。 \n\n 與以前的極低失調(diào)電壓、高壓放大器不同，OP1177（單通道）和OP2177（雙通道）放大器提供小型8引腳表面貼裝MSOP和8引腳窄體SOIC兩種封裝。OP4177（四通道）放大器提供TSSOP和14引腳窄體SOIC兩種封裝。此外，采用MSOP和 ? 低失調(diào)電壓：60 μV（最大值）\n\n? 極低失調(diào)電壓漂移：0.7 μV/°C（最大值）\n\n? 低輸入偏置電流：2 nA（最大值）\n\n? 低噪聲：8 nV/√Hz（典型值）\n\n? 共模抑制比(CMRR)、電源抑制比(PSRR)和AVO：> 120 dB（最小值）;
