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.
