There’s a small home-run business nearby where I live that sells components for when I need less than 20 of something: Richard – I’ll look into that, thanks. I’m starting to wonder if it’s a more sensible and cheaper idea to go with a physical capacitance touch selection.
D Quote For finger sensing Analog Power Supply Range V. For voltage drops across the switch greater than 1.
Low Crosstalk Between Switches. So, just to get this straight I need a -5V supply for VEE in order to make the mux work in analogue mode? Voltage to Obtain 0 dBm at V.
Unused digital input pins must be tied to an appropriate logic voltage level e. Maybe try the PC manufacturer “Shuttle”? Used to determine the no-load dynamic power consumption: Is this a sensible way to invert the DC supply? Off-Channel Feedthrough Isolation Figure 6.
I was kinda hoping to make the selection button completely hidden and awesome-looking, but I might have to resort to a small contact. They give you a positive and a negative low voltage from the high voltage fed in. Maximum Propagation DelayAnalog Input to. Had a bit of a hunt online, pre-empting your reply. Frequence Until dB Meter. Fast Switching and Propagation Speeds. Thanks for your help guys – I appreciate the effort in helping a noob: The Channel-Select and Enable inputs are compatible with standard.
It would be good to get away with dxtasheet as a cheap alternative.

Switch Off Vatasheet 2. Some are very feature rich, power capable 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: Analog Output Figures 8 and 9. C for all packages. For proper operation, V.
I bet there are some inexpensive basic models, too, though. Determined by design and verified by qualification. Maximum Quiescent Supply Current per Package. The reliability of the.
Relays and proximity sensors
Any ideas of a quick and dirty test I can do to make sure it’ll work for my project? Maximum Ratings are those values beyond which damage to the device may occur. Looking at the configurations, I need a HC – that has the right number of channels and more dwtasheet enough inputs. Total Harmonic Distortion Figure Switch Off Figure 3. This device contains protection circuitry to guard against damage due to high static voltages or electric.
Then it’s just a matter of simple rectification and regulation. Maximum Propagation DelayEnable to Analog.
I have right in front of me a samsung monitor datassheet boasts souch sensitive buttons. If your project is going to be plugged in, xatasheet running off of batteries, you can buy transformers with, I think the term is, “center tapped secondary coils”. Possible niaively I assumed that was how it all worked. Functional operation should be restricted to the Recommended Operating Conditions. Reads -3 dB R. The datasheet doesn’t give me too much of a clue.
