LSK389 Series Dual N-Channel JFETs

Linear Integrated Systems' flagship JFET dominates the high-end audio and sensor industries

Image of Linear Integrated Systems' LSK389 Series Dual N-Channel JFETsLinear Integrated Systems' LSK389 series is an ultra-low-noise dual junction field effect transistor (JFET) with models including LSK389A, LSK389B, LSK389C, and LSK389D. The models are graded by IDSS. The LSK389B grade model is designed for ultra-high-end systems, ranging from U.S. Navy underwater listening to studio reference amps and microphones.

These JFETs are individually tested for noise to ensure datasheet compliance. The two halves of the dual are interwoven using a proprietary design for optimal matching characteristics.
