Why Engineers Are Still Using Discrete JFETs

Integrated circuits continue to advance, but many of the highest-performance analog front ends still begin with a discrete JFET.

Why?

Because when you're trying to capture extremely weak signals, the input stage often determines the performance of the entire system.

Engineers continue to choose discrete JFETs for applications requiring:

• Ultra-low noise

• High input impedance

• Low input capacitance

• Excellent linearity

  
  

Whether designing photodiode amplifiers, hydrophone preamplifiers, precision sensor interfaces, or instrumentation front ends, these characteristics can make the difference between detecting a signal—or missing it.

That's why devices like the LSBF862, LSK170, LSK389, and LSK489 continue to be designed into new systems where signal integrity starts at the input stage.
