Dual, low-noise JFET has low capacitance and high input impedance

August 28, 2013 // By Steve Taranovich
Linear Integrated Systems' LSK489 is an N-channel monolithic dual JFET with 1.8 nV/√Hz noise at 1 kHz and low-capacitance (Ciss= 4 pF) . This lower capacitance will greatly improve intermodulation distortion with increasing frequency with the help of the JFET’s 1 TΩ input impedance.
