SST403 LOW NOISE, LOW DRIFT MONOLITHIC DUAL N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix SST403 The SST403 is a Low Noise, Low Drift, Monolithic Dual N-Channel JFET The SST403 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 SST403 features a 5mV offset and 10-µV/°C drift. The SST403 is a direct replacement for discontinued Siliconix SST403. The 8 Pin P-DIP and 8 Pin SOIC provide ease of manufacturing, and the symmetrical pinout prevents improper orientation. (See Packaging Information).
SST403 Applications:
Wideband Differential Amps High-Speed,Temp-Compensated Single-Ended Input Amps High-Speed Comparators Impedance Converters and vibrations detectors.
