LSK389 datasheet

 

Description :

The LSK389 is the industry’s lowest noise Dual NChannel JFET, 100% tested, guaranteed to meet 1/f and broadband noise specifications, while eliminating burst (RTN or popcorn) noise entirely. The LSK389 Series, Monolithic Dual N-Channel JFETs were specifically designed to provide users a better performing, less time consuming and cheaper solution for obtaining tighter IDSS matching, and better thermal tracking, than matching individual JFETs.
