I DONT HAVE A INFORMATION ON THEM !!!!! what goin on???

 

[Jay]

YOU MUST BE JOKING!

I have some of the ICs so I know I got the pdf from Googling.
In front of me is an STK405 chip and the pdf

 

[Dirk]

Half of them is here: http://www.datadart.com/al/sanyo/ (took me about 30 seconds in Google)

... and if you don't find information on some, it's probably a good indication they're not available anyway ...

[Hayden]

Any data sheet on the stk410-030k I.C I can't find it anywere

 

[Stocker]

I'm still looking, but has anybody found the datasheet for STK040-071?

I have the chip, but not the datasheet!

 

[hotwaterwizard]

STK403-130 Looking for the Datasheet.
Any Ideas?

 

[hotwaterwizard]

Here is a Datasheet that may be close to STK040-071

http://www.audiolabga.com/pdf/STK040.pdf

 

[Stocker]

I figured out from a table found on another datasheet that the -070 is 60-ish watts, and I'm going to call it close enough to that for me, since the -xx1 variants seem to be simlarly-rated for power output to the -xx0 versions.

Of course, the proof is in the pudding and I will have to measure it directly when the whole thing is all completed...

 

[rodolfo]

this ???

stk 402-series
stk402-020-------------120

 

[rodolfo]

& this???

stk412-series
stk412-090------------170

 

[hotwaterwizard]

I am still looking for most of these Datasheets. Beginning to wonder if some of them exist or not.
STK410 Series can not be found anywhere

 

[shon35us]

STK412-150?

Can you bridge this guy?

 

[pacificblue]

If you have speakers with more than 12 Ohm.

 

[shon35us]

Bridged

If you have speakers with more than 12 Ohm.

So, for any bridged output you need to have double the normal output in ohms. Example if the output in ohm is 8, for the same setup for bridged in would have to be 16 ohms for the same amp?

 

[pacificblue]

Yes, because each half of the bridge only sees half the impedance. A bridged 16 Ohm load appears as 8 Ohm for each half of the bridges.

If you want to use lower impedance, you need to put two bridged amps in parallel or use lower supply voltage which leads to lower output power.

 

[butterflytoan]

Hi, I can't find anywhere have datasheet of STK490-310, STK490-040S.
Anyone help me? Thanks

 

[raindog]

I just want to point out that this chips have long been discontinued by the original manufacturers ( Toshiba, Sony, Aiwa etc ) and what you can find on the market now are ic's ,,made in China" or , if you're lucky , NOS ic's . That's why in some cases it's hard to find a datasheet .
