LSK489 Series


The LSK489 is the industry’s lowest input capacitance and low-noise monolithic dual N-Channel JFET. Low input capacitance substantially reduces intermodulation distortion. In addition, these dual JFETs feature tight offset voltage and low drift over temperature range, and are targeted for use in a wide range of precision instrumentation and sensor applications. This part is available in the TO-71 6L, SOIC 8L, SOT-23 6L and DFN 8L package, as well as in die form.

Advanced screening options are available for our diverse product lineup, featuring JFETS, Bipolar transistors, MOSFETs, current regulators, and Diodes. Our special screening covers all the parameters listed in the standard datasheet, including comprehensive package pin-out.
