LS30 – Rotary Encoder Debounce IC Overview Video
Joe Farr, the Chief Engineer at LogiSwitch, introduces the LS30 Rotary Encoder Switch Debounce IC in a video. The LS30, leveraging NoBounce™ Technology, effectively debounces noisy mechanical rotary encoders. Designed for various encoder types, it’s particularly valuable for mechanical versions prone to signal bounce.
He discovered the LS30. “it worked great with way fewer components.” His rotary encoder switch bounce issues went away resulting in smooth operation. He commented: “these knobs feel great to turn.”

“I designed and built two different switch and lamp panels that allowed our software developer to simulate solenoids and position sensors to test their code before any machine was built. LogiSwitch NoBounce technology allowed me to connect them directly to the microcontroller with no debouncing software or hardware required. Their toggle and momentary functions were both used.”

“I love the LogiSwitch LS19! Before I found it, I was using simple RC debounce (2 resistors, 1 cap per channel) plus software debounce. Your chip replaces 18 parts with 2 solder pads each. It reduces our customers’ soldering by over 50% and performs so much better. The LS19 IC is used to debounce the mechanical footswitches and encoders which are both notorious for being rather bouncy and generally don’t play well with microcontrollers without some kind of hardware debounce.”

“LogiSwitch worked with our engineering team to come up with an outstanding solution based on their NoBounce technology that met our design goals and quality standards. During our extensive lifecycle testing, we completed a series of tests culminating in a greater than 100,000 count lifecycle equivalence without a LogiSwitch board failure.”
