| LSU405 LOW NOISE, LOW DRIFT MONOLITHIC DUAL N-CHANNEL JFET Linear Systems replaces discontinued Siliconix U405 with LSU405 The U405/ LSU405 is a Low Noise, Low Drift, Monolithic Dual N-Channel JFET The LSU405 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 LSU405 features a 5mV offset and 10-V/C drift. The LSU405 is a direct replacement for discontinued Siliconix U405. The hermetically sealed TO-71 & TO-78 packages are well suited for military applications. . (See Packaging Information).
