DESCRIPTION  
The low cost SST3958NL and U3958NL JFET duals are  
designed for high-performance differential amplification for a  
wide range of precision test instrumentation applications. This  
series features tightly matched specs, low gate leakage for  
accuracy, and wide dynamic range with IG guaranteed at  
VDG = 20 V.  
The U3958NL in the hermetically-sealed TO-78 package is  
available with full military processing.  
The SST3958NL in the SO-8 package provides ease of  
manufacturing. The symmetrical pinout prevents improper  
orientation. The SST3958NL is available with tape-and-reel  
options for compatibility with automatic assembly methods.  
Pins 4 and 8 on the SST3958NL and pin 4 on the U3958NL part  
numbers enable the substrate to be connected to a positive,  
external bias (VDD) to avoid latchup.
