OP400是一款提供OP77型性能的單芯片四通道運算放大器。該器件雖然集成了四個通道，提供節(jié)省空間和成本的優(yōu)勢，但并不影響其精密性能。 \n\n 整個軍用溫度范圍內(nèi)，OP400具有小于150 μV的極低輸入失調(diào)電壓，漂移小于1.2 μV/°C。開環(huán)增益超過500萬（10 kΩ負載），輸入偏置電流低于3 nA，共模抑制(CMR)高于120 dB，電源抑制比(PSRR)小于1.8 μV/V。OP400的低輸入失調(diào)電壓通過片內(nèi)齊納擊穿(Zener zap)調(diào)整而實現(xiàn)，無需進行失調(diào)零點校準。它采用業(yè)界標準四邊引腳排列，沒有調(diào)零引腳。\n\n OP400具有低功耗特性，每個放大器耗用的電源電流低于725 μA。該四通道放大器的總功耗低于單通道OP07，而性能則明顯優(yōu)于這款工業(yè)標準運算放大器。OP400的電壓噪聲密度在10 Hz時為11 nV/√Hz，僅為大多數(shù)競爭器件的一半。\n\n OP400是需要多個精密運算放大器和低功耗應(yīng)用的理想選擇。\n\n數(shù)據(jù)手冊，Rev.
