Fred if I may be so bold – I have been looking at your schematic and was wondering how different the s are that I have? Thats excellent – just what I was wondering – thank you muchly! I use a pair of the 2SK single in place of 2s74 K all the time, and yes, I do buy them in 10k quanities. So what else can be used when they are all gone??

December 21, Started by zebra50 The Lab. Started by analag The Lab.

I’m guessing its a lot. I’ll check them out. I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design I will try to get a load of s before there all gone 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.

The product line includes: Toll Free Phone: And J for switching? I’m bummed that Toshiba has discontinued these and not offered a replacement.

May 21, Just a little bump up, with a question. 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.

However, I still use the K in critical locations. Or would a couple of 2SK still offer comparable noise performance compared to the LM? 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.

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

Should be able to get really low datsaheet and offset with these. Thanks that’s exactly what I meant: Tom, I am looking at the November time frame to get one thousand. Not that the makes a poor line level device Please state the specific application in which you desire to use them. When used together, the LSJ and LSK are ideal for differential input stages for amplifier, phono, and preamplifier designs.

February 25, The main amplifer in the buffer will be a Datasheft Thats great stuff Tamas – cheers!

Linear Integrated Systems for assistance with application or special testing issues. I’m not asking for you to share any precious circuit diagrams, datashset curious what other features you have added?

Additional applications for the LSJ include voltage controlled resistors, thermal stable source followers, sample and hold, and current matched sources. I was wondering if anyone knows of any JFET chips that feature a similiar number 50! 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.

Thanks for the tip Charlie! But I will be using datashedt devices in hopefully an instrumentation based amp for line level buffering. LIS is a U. Hey Tamas – that sure sucks It seems to me that all the good audio parts are 2zj74 discontinued – don’t you find it worrying that you may not be able to build your in the near distant future? I’m going to compare specs from the datasheets I’ve never purchased from them, so I can’t vouch for them as a company.

I remember thinking something similar when datasheeg the PDF. Currently I am concentrating stashing away a couple of hundred of 2SKs. Thanks a lot Fred!
