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.
