U440 MONOLITHIC DUAL N-CHANNEL JFET Linear Systems replaces discontinued Siliconix U440 The U440 is a tightly matched Monolithic Dual N-Channel JFET The U440 are monolithic dual JFETs mounted in a single TO-71 package. 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 U440 is a direct replacem
