LS5911 MONOLITHIC DUAL N-CHANNEL JFET Linear Systems replaces discontinued Siliconix & National 2N5911 FEATURES Improved Direct Replacement for SILICONIX & NATIONAL 2N5911 LOW NOISE (10KHz) en~ 4nV/√Hz HIGH TRANSCONDUCTANCE (100MHz) gfs ≥ 4000µS ABSOLUTE MAXIMUM RATINGS 1 @ 25°C (unless otherwise noted) The LS5911 are monolithic dual. The monolithic dual chip design reduces parasitics and gives better performance at very high frequencies while ensuring extremely tight matching. These devices are an excellent choice for use as wideband differential amplifiers in demanding test and measurement applications. The LS5911 is a direct replacement for discontinued Siliconix and National 2N5911. Maximum Temperatures Storage Temperature Operating Junction Temperature Maximum Power Dissipation Continuous Power Dissipation (Total) Maximum Currents Gate Current Maximum Voltages Gate to Drain Gate to Source The hermetically sealed TO-78 is well suited for military and harsh environment applications. (See Packaging Information). LS5911 Applications: Wideband Differential Amps High-Speed,Temp-Compensated SingleEnded Input Amps High-Speed Comparators Impedance Converters and vibrations detectors.
