LS846
N-CHANNEL JFET
Linear Systems Low Leakage Low Noise JFET
The LS846 is a high-performance JFET featuring
extremely low noise and low leakage and is targeted for
use in a wide range of precision instrumentation
applications.
The 8 Pin P-DIP and 8 Pin SOIC provide ease of
manufacturing, and the symmetrical pinout prevents
improper orientation.
(See Packaging Information).
