Overview: 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 replacement for discontinued Siliconix U440. The hermetically sealed TO-71 is well suited for military applications. (See Packaging Information). U440 Applications: Wideband Differential Amps High-Speed,Temp-pensated SingleEnded Input Amps High-Speed parators Impedance Converters and vibrations detectors.
