Hi,<br>The chip I'm using is the TLC 5540.<br>It samples at 40Mhz which gives a usable bandwidth of 8Mhz- fine for Video- which is my main application. I just terminate my 2Volt video signal with a resistor and get great results. For larger voltages you could try a resistor network. For other uses, like a dc offset, things get more advanced- check this out: <a href="http://alternatezone.com/electronics/dsoamk3.htm">http://alternatezone.com/electronics/dsoamk3.htm</a><br>
<br>I'm looking to have some pcb's made up to go with my propeller protoboard. Functionality would include:<br>- 2 h-bridges<br>- 3 Axis digital Accelerometer<br>- 40Mhz ADC with input from BW camera<br>These would be for beta kits of the dancebots, but could be used to built pretty cool robots or just be used for Video/Analog input into the Propeller.<br>
<br>Anyone interested? Where should I have them made? I've heard good things about goldphoenixpcb.biz...<br>Hanno<br><br><br><div class="gmail_quote">On Sat, Mar 1, 2008 at 4:08 PM, Chris Hellyar <<a href="mailto:chris@trash.co.nz">chris@trash.co.nz</a>> wrote:<br>

<br>
How would you go for an analog front end on this if you were to DIY a<br>
scope? Or were you just thinking about using it for low voltage stuff<br>
where isolation & input range isn't so much an issue?<br>
<br>
I'm thinking large DC offsets, like 80 vdc offset, looking for a 5 volt<br>
signal..<br>
