LS5912C MONOLITHIC DUAL N-CHANNEL JFET Linear Systems replaces discontinued Siliconix & National 2N5912C FEATURES Improved Direct Replacement for SILICONIX & NATIONAL 2N5912C LOW NOISE (10KHz) en~ 4nV/√Hz HIGH TRANSCONDUCTANCE (100MHz) gfs ≥ 4000µS ABSOLUTE MAXIMUM RATINGS 1 @ 25°C (unless otherwise noted) The LS5912C are monolithic dual JFETs. 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 LS5912C is a direct replacement for discontinued Siliconix and National LS5912C. 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 8 Pin P-DIP provides ease of manufacturing, and the symmetrical pinout prevents improper orientation. (See Packaging Information). LS5912C Applications: Wideband Differential Amps High-Speed,Temp-Compensated SingleEnded Input Amps High-Speed Comparators Impedance Converters and vibrations detectors.
