Then it’s just a matter of simple rectification and regulation. And another source to explore would be the suppliers of lab bench power supplies. Search field Part name Part description. The Channel-Select and Enable inputs are compatible with standard. Maximum Ratings are those values beyond which damage to the device may occur. For voltage drops across nc4052 switch greater than 1.

Off-Channel Feedthrough Isolation Figure 6. Output Datassheet 12 and I’m starting to wonder if it’s a more sensible and cheaper idea to go with a physical capacitance touch selection.

Maybe try the PC manufacturer “Shuttle”? When the Enable pin is high, all analog switches are turned off. I’m learning as I go having only done an AS level in electronics over 15 years ago where I learned nothing – I’m much more at home with a C compiler: Had a bit of a hunt online, pre-empting your reply. I’d expect that sticking a multimeter across the common for one channel Xand the first input for that channel X0 to test connectivity, I would be able to make and break a physical connection between the pins.


Datasheeet reliability of the. It would be good to get away with this as a cheap alternative. Switch Off Figure 3. Used to determine the no-load dynamic power consumption: Switch Off Figure 2. Some are very feature rich, power capable D Quote For finger sensing Low Crosstalk Between Switches. Fast Switching and Propagation Speeds. Thanks for your help guys – I appreciate the effort in helping a noob: For proper operation, V.

I bet there are some inexpensive basic models, too, though. Voltage to Obtain 0 dBm at V. You could buy one intended for a “quiet” computer Maximum Propagation Delay, Channel-Select to. This device contains protection circuitry to guard against damage due to high static voltages or electric.

Reads -3 dB R. Is this a sensible way to invert the DC supply? Static or Dynamic Voltage Across Switch.

I was kinda hoping to make the selection button completely hidden and awesome-looking, but I might have to resort to a small contact. Richard – I’ll look into that, thanks.


Maximum Propagation DelayEnable to Analog. There’s a daasheet home-run business nearby where I live that sells components for when I need less than 20 of something: Determined by design and verified by qualification.

Analog Output Figures 8 and 9. Possible niaively I assumed that was how it all worked. If your project is going to be plugged in, vs running off of batteries, you can buy transformers with, I think the term is, “center tapped secondary coils”.

Any ideas of a quick and dirty test I can do to make sure it’ll work for my project? Maximum Propagation DelayAnalog Input to. Looking at the configurations, I need a HC – that has the right hc40522 of channels and more than enough inputs. Functional operation should be restricted to the Recommended Operating Conditions.
