The LSU426 monolithic dual n-channel JFET is
designed to provide very high input impedance for
differential amplification and impedance matching.
Among its many unique features, this series offers
operating gate current specified at -500 fA. The
LSU426 is a direct replacement for discontinued
Siliconix U426.
