LSK 170B, Single N-chanel Ultra Low Noise JFET Transistor

Beskrivning

LSK 170B Ultra Low Noise JFET

The LSK170 is the single counterpart to the LSK389 and achieves similar ultra-low-noise performance. Like all high-performance Linear Systems single JFETs, the LSK170 uses a gold backside contact to enhance low noise and low leakage performance. The LSK170 is used in a variety of applications ranging from studio microphones to sonobuoys.

Application Note

LSK 170 och LSJ 74 är en klassisk transistor.  Toshiba lanserade en gång 2SK170/2SJ74 men de finns inte längre. Numera tillverkar Linear Systems dessa produkter.
Dessa lågbrusiga transistor finns i många proffs apparater men det finns även massor av konstruktioner för DIY marknaden. En verkligt klassisk applikation är phonoförstärkaren, som kräver lågt brusvärde.

Linear Systems presents a full line of single, dual, N-Channel and P-Channel ultra-low-noise JFETs to create low-noise, high-performance applications ranging from sensors to audio amplifiers. Members of the company’s design and production staff each have over 40 years’ experience making these parts, and as a group they are the most talented working in this area today.

Linear Systems has unique expertise in designing and producing monolithic dual JFETs, with related intellectual property dating back to the beginning of the company over 30 years ago. Monolithic dual JFETs have a very real and significant thermal tracking advantage over two discrete die selected for match in the same package. Selecting two dice for VGS match isn’t hard, but it is far more difficult to select VGS match over a temperature span.

Linear Systems’ monolithic dual designs overcome the typical problem with this approach – parasitic capacitance – to create the highest performance parts in their class. Our proprietary JFET designs also create the lowest noise parts of their type in the industry.
