N-Channel Dual JFET

CORPORATION

U421 – U426

FEATURES

DESCRIPTION

Ultra Low Input Bias Current . . . . . . . 250 Fempto Amps

Low Operating Current

Tight Matching Characteristics

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.
