LSK389
ULTRA LOW NOISE
MONOLITHIC DUAL
N-CHANNEL JFET
Linear Systems replaces discontinued Toshiba 2SK389 with LSK389
The 2SK389 / LSK389 is a monolithic matched dual JFET on a single chip
Why use On-Chip Dual JFET instead of 2 single JFETS?
Save Cost
2SK389 / LSK389 removes significant cost for test screening time
needed to match I
DSS
on 2 individual JFETS and offers ZERO
yield loss.
Improve Performance
2SK389 / LSK389 On-Chip I
DSS
matching gives closest possible
synchronous electrical performance and also offers better
matched performance when the chip is subjected to temperature.
2SK389 / LSK389 Applications:
End audio microphone, Audio Amplifier and audio effects box
manufacturers
Instrumentation-input stages of various instruments
The acoustic sensor market –sonoboys / antisubmarine, military
personnel and vehicle detectors, sonar makers. Radiation
detectors.
