Vishay Semiconductors DGQ2788A双通道双刀双掷/四通道单刀双掷模拟开关
Vishay Semiconductors DGQ2788A 0.37Ω、338MHz带宽、双通道双刀双掷/四通道单刀双掷模拟开关具有四个通道和两个控制输入。DGQ2788A采用四通道单刀双掷 (SPDT) 模拟开关和双通道双刀双掷 (DPDT) 配置。该开关在两个方向均具有出色的导通能力。这样即可实现轨到轨信号切换,也可用作多路复用器以及多路分解器。该器件在整个信号范围内均具有高度平坦且匹配的低开关电阻,以及低寄生电容。特性包括先断后合开关、低控制逻辑阈值,以及支持轨到轨快速脉冲信号的0.1ns(典型值)传播延迟。DGQ2788A能够高效利用电路板空间,非常适合用作空间受限应用的模拟和数字信号开关。该器件采用小型QFN-16封装,尺寸为2.6mm x 1.8mm x 0.55mm,符合汽车电子委员会 (AEC) Q100标准(1级)。特性
