LS4119A

N-CHANNEL JFET

Linear Systems replaces discontinued Siliconix 2N4119A

The LS4119A is an Ultra-High Input Impedance N-Channel JFET

FEATURES

The LS4119A provides ultra-high input impedance. The

device is specified with a 1-pA limit and typically

operates at 0.2 pA. The part is ideal for use as a high-

impedance sensitive front-end amplifier.

1 . Absolute maximum ratings are limiting values above which LS4119A serviceability may be impaired.

2. Due to symmetrical geometry, these units may be operated with source and drain leads interchanged

3. This parameter is measured during a 2ms interval 100ms after power is applied. (Not a JEDEC condition.)
