LSK389 Series


The LSK389A, B, C and D grades of high performance monolithic dual JFETs feature extremely low noise, tight offset voltage and low drift over temperature specifications, and is targeted for use in a wide range of precision instrumentation applications. This series has a wide selection of offset and drift specifications. This high-performance, ultra-low-noise dual N-Channel JFET amplifier is the only 100-percent noise tested JFET available and provides the optimal balance between very low noise (en =1.3nV/√Hz) and input capacitance (Ciss = 25pF). Available in TO-71 6L, SOIC 8L, as well as die form.

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