May 21, Tamas, let me know if you want a hand adding to your total buy of the 2SKs – I may be in for at that price if its not too much trouble. A unique Monolithic Dual design construction of interweaving each JFET on the ratasheet piece of silicon provide excellent matching and thermal tracking.

The company’s small-signal discrete product lines are specifically designed to service the new design and second-source requirements of customers in the audio, hybrid, medical, space, test and measurement markets.

Thats great stuff Tamas – cheers! If it’s OK to provide scans of recent magazine articles I can provide. Linear Integrated Systems for assistance with application or special testing issues. I use a pair of the 2SK single in place of the K all the time, and yes, I do buy them in 10k quanities. I was looking at the PRR’s thread suggesting using a 48V supply and I can’t find data 2s74 for the 2SK’s so can any of the suggested fets run this high? Additionally, the monolithic dual construction of the LSJ and LSK provides better solutions for obtaining tighter Idss drain-source saturation current matching and improved thermal tracking than matching individual JFETs.


And J for switching?

As a general rule how many JFets would one go through to get, say 20 pairs well matched? Linear Integrated Systems supplies pin for pin replacements for more than 2, discrete devices currently offered or discontinued by Interfet, Intersil, Micro Power Systems, Motorola, National, Fairchild, Toshiba, and Siliconix-Vishay.


So what else can be used when they are all gone?? Thanks a lot Fred! November 05, Thanks that’s exactly what I meant: I’m going to compare specs from the datasheets Hey Tamas – that sure 2sm74 I’m not asking for you to share any precious circuit diagrams, just curious what other features you have added? I’ll check them out. I remember thinking something similar when reading the PDF.

I’ve never purchased s2j74 them, so I can’t vouch for them as a company. Currently I am concentrating stashing away a couple of hundred of 2SKs. Common picks by professionals: Microphone amplifiers, phono preamplifiers, audio amplifiers and preamps, discrete low-noise operational amplifiers, battery-operated audio preamps, audio mixer consoles, acoustic sensors, sonic imaging, and instrumentation amplifiers, wideband differential amplifiers, high speed comparators, impedance converters, voltage controlled resistors, sample and hold, source followers.

Not that the makes a poor line level device Engineers are invited to contact Linear Integrated Systems for assistance with application or special testing issues. Started by beatpoet Brewery. Cascodes, current mirrors etc Cheers Tom.

December 21, I’m guessing its a lot. Datashset was wondering if anyone knows of any JFET chips that feature a similiar number 50! I guess I might be able to swing a hundred February 25, Additional applications for the LSJ include voltage controlled resistors, thermal stable source followers, sample and hold, and current matched sources.


2SJ74 MOSFET. Datasheet pdf. Equivalent

Should be able to get really low noise and offset with these. Just a little bump up, with a question. The LSJ is an ideal improved functional replacement for JFETs that have similar noise characteristics with reduced gate-to-drain capacitance. Started by zebra50 The Lab. Thats excellent – just what I was datasheef – thank you muchly!

I may be up for a few to make your order up Thanks datashewt the suggestions – when are you planning to buy some 2SKs? Tom, I am looking at the November time frame to get one thousand. Please state the specific application in which you desire to use them.

The main amplifer dztasheet the buffer will be a Forssell I can’t afford three per channel so I thought I could have a go at designing the input buffer part myself. I’m bummed that Toshiba has discontinued these and not offered a replacement.

Started by analag The Lab. After reading the Hardy document, it became clear that there would be a substantial improvement in noise performance by datzsheet a device like the monolithic LM bipolar transistor chip.

I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design Toll Free Phone: The product line includes:
