Description
The LSK 489 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 or precision instrumentation applications. This series has
a wide selection of offset and drift specifications. The SST series SO-8 package provided 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. (See packaging data)
