The 2N3954A is a Low Noise, Low Drift, Monolithic Dual N-Channel JFET
2N3954A
MONOLITHIC DUAL
N-CHANNEL JFET
Note 1 – These ratings are limiting values above which the serviceability of any semiconductor may be impaired
2N3954A Applications:
Wideband Differential Amps
High Input Impedance Amplifiers
The 2N3954A family are matched JFET pairs for
differential amplifiers. The 2N3954A family of general
purpose JFETs is characterized for low and medium
frequency differential amplifiers requiring low offset
voltage, drift, noise and capacitance
The 2N3954A 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.
