DESCRIPTION
The Calogic U421 Series are Dual N-Channel JFETs on a
monolithic structure designed specifically for very high input
impedance for differential amplification and impedance
matching. This series features ultra low input bias current
(250 fempto amps, U421) while offering high gain at low
operating currents and tight matching characteristics. These
devices are available in chip form for hybrid designs as well
as a hermetic TO-78 package.
