2N5909
LOW NOISE, LOW DRIFT
MONOLITHIC DUAL
N-CHANNEL JFET
The 2N5909 is a high-performance monolithic dual
JFET featuring tight matching and low drift over
temperature specifications, and is targeted for use in a
wide range of precision instrumentation applications
where tight tracking is required.
The hermetically sealed TO-78 package is well suited
for hi-reliability and harsh environment applications.
(See Packaging Information).
