U440

MONOLITHIC DUAL

N-CHANNEL JFET

Linear Systems replaces discontinued Siliconix U440

The U440 is a tightly matched Monolithic Dual N-Channel JFET

FEATURES

The U440 are monolithic dual JFETs mounted in a

Direct Replacement for SILICONIX U440

HIGH CMRR

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.
