LS5912C

LS5912C MONOLITHIC DUAL N-CHANNEL JFET Linear Systems replaces discontinued Siliconix & National 2N5912C The LS5912C are monolithic dual JFETs. The monolithic dual chip design reduces parasitics and gives better performance at very high frequencies while ensuring extremely tight matching. These devices are an excellent choice for use as wideband differential amplifiers in demanding test and measurement applications. The LS5912C is a direct replacement for discontinued Siliconix and National LS5912C. The 8 Pin P-DIP provides ease of manufacturing, and the symmetrical pinout prevents improper orientation.
