FEATURES
DESCRIPTION
APPLICATIONS
Calogic’s SST440 Series is a high speed N-Channel
Monolithic Dual JFET in a surface mount SO-8 package. This
device is well suited for use as wideband differential amplifiers
in test and measurement applications. The combination of
high gain, low leakage and low noise make it an excellent
performer.
• High Gain . . . . . . . . . . . . . . . . . . . . . . . gfs > 6 mS typical
Leakage . . . . . . . . . . . . . . . . . . . . . . IG < 1pA typical
• Low
• Low Noise
• Surface Mount Package
Wideband Amplifiers
• Differential
• VHF/UHF Amplifiers
• Test and Measurement
