LSU404_TO-71

LSU404 LOW NOISE, LOW DRIFT MONOLITHIC DUAL N-CHANNEL JFET Linear Systems replaces discontinued Siliconix U404 with LSU404 The U404/ LSU404 is a Low Noise, Low Drift, Monolithic Dual N-Channel JFET The LSU404 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 LSU404 features a 5mV offset and 10-µV/°C drift. The LSU404 is a direct replacement for discontinued Siliconix U404. The hermetically sealed TO-71 & TO-78 packages are well suited for military applications. (See Packaging Information).
