Hi:
I have several months searching for R2R networks, (SIP with 10 pins) to use them in some DAC applications.
Somebody knows where can I get them?
I had made exaustive search on Internet. I even get a Bourns number, but I had not found in any distributor. The value to use is 10K.
Please help...

Hi:
I did check Mouser and Bourns and they do not have any.
The Bourns number I had was 4116R-R2R-103.
Thanks anyway...

I Googled your part number and it returned 4 pages of links, these three appear to sell the part number you specified. Is there some reason a substitute will not work? These SIPS are generally pretty generic, either common to one pin or all seperate. Mouser does indeed sell resistor networks as do many others.

the 4116r-r2r-103 seems to be a discontinued unit here is a link to the datasheet for comparison to substitutes.

Hi:
I did search in Goggle and even put quoting requests in several, and I got emais with "out of stock" response.
The families found at Bourns, are resistor and terminatos, but not R2R.
I am really intrigued ... Nobody uses R2R...?
Thanks...
