Those AD chips do just what I need... But only come in 80 pin
SMD... The price can be overcome, but not the 80 pins methinks..<br><br><div><span class="gmail_quote">On 11/7/05, <b class="gmail_sendername">Jeff Farr</b> <<a href="mailto:moogah@gmail.com">moogah@gmail.com</a>> wrote:

At this moment I have no spec for what unconnected outputs must be, but
I believe they will have to float. Mind you this is for analog
signals, not digital. The purpose of this being a switch matrix
to route CV signals around a synth. <div><span class="e" id="q_1076df529f453e81_1"><br><br><div><span class="gmail_quote">On 11/7/05, <b class="gmail_sendername">Paul Schreiber</b> <<a href="mailto:synth1@airmail.net" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

[sdiy] What type of switch would this be?</div>
<div><br></div>I need an IC that has one input that can be sent to any
number of it's outputs, ie in->out1 or in->out1 & out 2.
Can a mux do this? What If I need a total of more than 40
outputs? (ouch). Looking over datasheets I'm begging to
think I need to create a massive swich array out of smaller parts and then
use a uC to do the switching, I had at first assumed there would be
something available to the effect of having a 4bit input to determine the
output
connetions..<br></blockquote></span></div></blockquote></div><br></span></div></blockquote>
