LSU402
LOW NOISE, LOW DRIFT
MONOLITHIC DUAL
N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix U402 with LSU402
The U402/ LSU402 is a Low Noise, Low Drift, Monolithic Dual N-Channel JFET
FEATURES
LOW DRIFT
LOW NOISE
LOW PINCHOFF
The LSU402 is a high-performance monolithic dual
| V GS1‐2 / T| = 10µV/°C TYP.
en = 6nV/Hz @ 10Hz TYP.
Vp = 2.5V TYP.
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 LSU402 features a 5-
mV offset and 10-µV/°C drift. The LSU402 is a direct
replacement for discontinued Siliconix U402.
