The LSU403 is a Low Noise, Low Drift, Monolithic Dual N-Channel JFET
LSU403
LOW NOISE, LOW DRIFT
MONOLITHIC DUAL
N-CHANNEL JFET
LSU403 Applications:
Wideband Differential Amps
High-Speed,Temp-Compensated Single-Ended
Input Amps
High-Speed Comparators
Impedance Converters and vibrations detectors.
The LSU403 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 LSU403 features a 5-
mV offset and 10-µV/°C drift. The LSU403 is a direct
replacement for discontinued Siliconix LSU403.
The 8 Pin P-DIP and 8 Pin SOIC provide ease of
manufacturing, and the symmetrical pinout prevents
improper orientation.
(See Packaging Information).
Linear Systems replaces discontinued Siliconix U403
Note 1 – These ratings are limiting values above which the serviceability of any semiconductor may be impaired
