Specialty linear semiconductor maker, Linear Integrated Systems, has released the LSK389 series of 1 nV N-Channel Monolithic Dual JFETs. This is a dual version of its LSK170 Single N-Channel JFET. This family of ultra low noise dual JFETs was 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, states the company. The LSK389's features incorporates three grades of IDSS: 2,6-6,5 mA, 6,0-12 mA, 10-20 mA, with an IDSS match of 10%, a gate threshold offset of 20 mV, a voltage noise (en) of 1 nV/Hz @ 1 kHz, 2 nV/Hz @ 10 Hz typical, with a gain (Yfs) of 22 mS, and 22 pF of capacitance. It comes in RoHS surface mount SOIC-8 and through-hole TO-71 packages.
