U426 HIGH INPUT IMPEDANCE MONOLITHIC DUAL N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix U426
The U426 is a high input impedance Monolithic Dual N-Channel JFET
The U426 monolithic dual n-channel JFET is designed to provide very high input impedance for differential amplification and impedance matching. Among its many unique features, this series offers operating gate current specified at -500 fA. The U426 is a direct replacement for discontinued Siliconix U426. The hermetically sealed TO-71 & TO-78 packages are well suited for military applications. The 8 Pin P-DIP and 8 Pin SOIC provide ease of manufacturing, and the symmetrical pinout prevents improper orientation. (See Packaging Information).
