DESCRIPTION
The SST/U401NL series of high-performance monolithic dual
JFETs features extremely low noise, tight offset voltage and
low drift over temperature specifications, and is targeted for
use in a wide range of precision instrumentation applications.
This series has a wide selection of offset and drift
specifications with the U401NL featuring a 5-mV offset and
10-mV/_C drift.
numbers enable the substrate to be connected to a positive
polarity, external bias (VDD) to avoid latchup.
The U series, hermetically sealed TO-78 package is
available with full military processing. The SST series SO-8
package provides ease of manufacturing, and the
symmetrical pinout prevents improper orientation. The SO-8
package is available with tape-and-reel options for
compatibility with automatic assembly methods.
Pins 4 and 8 of the SST series, and pin 4 of the U series part
