J211
N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix J211
The J211 is a n-channel JFET General Purpose
amplifier with low noise and low leakage.
The SOT-23 package is well suited for cost sensitive
applications and mass production.
(See Packaging Information).
J211 Benefits:
ƒ High gain
ƒ Low Leakage
ƒ Low Noise
J211 Applications:
ƒ General Purpose Amplifiers
ƒ UHV / VHF Amplifiers
ƒ Mixers
ƒ Oscillators
