Linear Systems Ultra Low Leakage Low Drift Monolithic Dual JFET
The LS833 is a high-performance monolithic dual
JFET featuring extremely low noise, tight offset voltage
and low drift over temperature specifications, and is
targeted for use in a wide range of precision
instrumentation applications. The LS833 features a 25mV offset and 75-µV/°C drift.
The 6 Pin SOT-23 package provides ease of
manufacturing, and a lower cost assembly option.
(See Packaging Information).
LS833 Applications:
Wideband Differential Amps
High-Speed,Temp-Compensated SingleEnded Input Amps
High-Speed Comparators
Impedance Converters and vibrations
