@ 25°C (unless otherwise noted)
The 2N5905 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.
| VGS1‐2 / T| = 5µV/°C TYP.
IG = 150fA TYP.
Vp = 2V TYP.
The hermetically sealed TO-78 package is well suited
for hi-reliability and harsh environment applications.
