U290
U290 SERIES
N-Channel JFET
~Siliconix
~ incorporated
The U290 Series is a high-performance JFET analog
switch which offers ultra low on-resistance and fast
switching. It features the lowest available
on-resistance of any JFET available in the industry
today. It is packaged in a hermetically sealed
TO-52 can which makes it suitable for military
applications. (See Section 1 for details.)
For further design information please consult the
typical performance curves NVA which are located
in Section 7.
