SST5911
MONOLITHIC DUAL
N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix & National SST5911
FEATURES
The SST5911 are monolithic dual JFETs. The
Improved Direct Replacement for SILICONIX & NATIONAL SST5911
monolithic dual chip design reduces parasitics and
gives better performance at very high frequencies while
ensuring extremely tight matching. These devices are
an excellent choice for use as wideband differential
amplifiers in demanding test and measurement
applications. The SST5911 is a direct replacement for
discontinued Siliconix and National SST5911.
