Linear Systems JFETs LS840 TO-78 6L ROHS

The LS840 is a monolithic dual N-channel JFET amplifier designed for low noise and low drift applications. It is packaged in a TO-78-6 through-hole case. The device has a maximum gate-to-source voltage of -60 V and a total power dissipation of 400 mW at 25°C. It features a typical transconductance of 500 µS at 200 µA drain current, a gate current of 10 pA at 25°C, and a typical input voltage noise of 8 nV/√Hz. The gate-source offset voltage is 2 mV typical, with a drift of 5 µV/°C maximum over the temperature range of -55°C to +125°C. The input capacitance is 4 pF typical, and drain-to-drain capacitance is 0.1 pF. The device meets operating and storage junction temperature ranges of -55°C to +150°C.
