The LSU401 is a Low Noise, Low Drift, Monolithic Dual N-Channel JFET

The LSU401 is a high-performance monolithic dual JFET featuring 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. The LSU401 features a 5-mV offset and 10-µV/°C drift. The LSU401 is a direct replacement for discontinued Siliconix LSU401.
The SOT-23 package provides ease of manufacturing, and a lower cost assembly option.
