LS846_SOIC

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).
