detectors.

Why use On-Chip Dual JFET instead of 2 single JFETS?

Save Cost

2SK389 / LSK389 removes significant cost for test screening time

yield loss.

Improve Performance

synchronous electrical performance and also offers better

matched performance when the chip is subjected to temperature.

Linear Systems replaces discontinued Toshiba 2SK389 with LSK389
