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. All devices are available with special testing to customer specifications.
