Product details

Description

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.

Features

Ultra Low Noise: en = 1.9nV/√Hz (typ), f = 1kHz and NBW = 1Hz.
Tight Matching: IVGS1-2I = 20mV max.
High Breakdown Voltage: BVGSS = 40V max.
High Gain: Gfs = 20mS (typ).
Low Capacitance: 25pF typ.
Improved Second Source Replacement for 2SK389 Benefits.
Unique Monolithic Dual Design Construction of Interleaving Both JFETs on the Same Piece of Silicon.
Excellent Matching and Thermal Tracking.
Great for Maximizing Battery Operated.
