LSK389 JFET Datasheet

Image
  Product Overview 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.   This blog will introduce   LSK389   systematically from its features, pinout to its specifications, applications, also including LSK389 datasheet and so much more.   LSK389   Features • Ultra Low Noise: en = 1.3nV/ √ Hz   (typ), f = 1.0kHz and NBW = 1.0Hz • Ultra Low Noise: 1.5nV/ √ Hz (typ),   f = 10Hz and NBW = 1.0Hz • Tight Matching:   IVGS1-2I = 15mV max • High Breakdown Voltage:   BVGSS = 40V max • High Gain: Gfs = 20mS (typ) • Low Capacitance: 25pF (typ) • Improved Second...
