Part Number: LSK389
Function: Ultra-Low Noise Monolithic Dual N-Channel JFET Amplifier
Package: PDIP, TO-71, TO-5, SOIC-8, SOT23-6 type
Manufacturer: Linear Integrated System
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.
Pin for Pin Replacements for Fairchild, Motorola, National, Siliconix-Vishay.
All Dual Devices are available in PDIP, TO-71, TO-5, SOIC-8, SOT23-6, Tested Die All Devices are available with special testing to customer specification.
