Control of analog signals up to the complete supply voltage range can be achieved. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. The reliability of the device will be unaffected unless the Maximum Ratings are exceeded.

When using these as a switched gain control or divider you have the opportunity to ground the common side giving you far far greater signal to noise ratio.

These muxes are dynamite for analog synth sequencers. You can gate trigger pulses, control voltages, and analog signal sources with equal ease. If you have the unused peripheral, a PWM through a multi-stage low pass filter works nicely as a dac.

I had to replace a defective in the keyboard of a Xerox II. Different The in this article is an analog switch. Nope, this board has both an microcontroller and a mux. As spacecoyote said, it really is a Second chip in from the upper left.

PS: Love you web site. I used one years ago for turning pixels on and off for a NTSC video overlay. I used a synch seperator to get the veritcal and horizontal timing from a cheap camera. Then I bit shifted each which only took one cpu cycle. The lookup and move took just enough cycles that it provided great spacing for the characters. It shows up in the datasheet as them having variable intrinsic resistance.

So yeah. They work like the on steroids. At one point I had a cheap 20 channel radio shack scanner with no search function. The computer I had available to me was a VIC Wrote a basic program to enter the key sequence for a range of frequencies and check the state of the squelch line.

It was slower than the much more expensive scanners but it did work. Had to think about it. I miss the scanners loaded with crystals. Top technology back in the day….

A bilateral switch is just two CMOS fets that are complimentary driven so that they conduct at either polarity or direction. They would work fine with switched filtering. They are not meant for significant currents. Many, many programmable-preset music synthesizers used and still use the x series. From panel reading multiplex to parameter setting demultiplex they are used in at least a hundred different machines.

After about seconds, the output from the dies. When I turn the power off and back on, it does the same thing over again — normal signal out then dies. Any ideas? It looks like Maxim got the idea and further refined it to almost perfection in MAX which has 0. But for higher price. Please be kind and respectful to help make the comments section excellent.

Now could i multiplex the input datasbeet to constant current circuit? Expected add to cart to know when it arrives.

Since i need to make a differential measurement between the first two leads of the pt while avoiding rds on of HC, i attached A0 of the ADC directly to the first wire through a schottky diode. Or reed relays could be another way? Arduino on other Chips. This website uses cookies to improve your experience while you navigate through the website.
