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 6 Pin SOT-23 package provides ease of
manufacturing, and a lower cost assembly option.
(See Packaging Information).
LS846 Applications:
 Wideband Differential Amps
 High-Speed,Temp-Compensated Single-
Ended Input Amps
 High-Speed Comparators
 Impedance Converters and vibrations
detectors.
