LS3954A MONOLITHIC DUAL N-CHANNEL JFET
The LS3954A is a Low Noise, Low Drift, Monolithic Dual N-Channel JFET
The LS3954A family are matched JFET pairs for differential amplifiers. The LS3954A family of general purpose JFETs is characterized for low and medium frequency differential amplifiers requiring low offset voltage, drift, noise and capacitance The LS3954A family exhibits low capacitance - 6pF max and a spot noise figure of - 0.5dB max. The part offers a superior tracking ability. The 8 Pin P-DIP and 8 Pin SOIC provide ease of manufacturing, and the symmetrical pinout prevents improper orientation. (See Packaging Information). FEATURES LOW DRIFT LOW LEAKAGE LOW NOISE ABSOLUTE MAXIMUM RATINGS @ 25°C (unless otherwise noted) |∆ VGS1‐2 /∆T|= 5µV/°C max. IG = 20pA TYP. en = 10nV/√Hz TYP.
