Pretty cool stuff!! TI is getting stronger in the analog domain with this kind of cool innovative products. I think there could be many promising ideas of using this device. The simplest one that occurs to me (which I would like to try) is making a cheapest, smallest metal detector gadget for fun. :)
Reminds me of one of my first major designs as a young 'un, a vehicle loop detector that was used in Western Australia for 15 years. The best compnent I had to work with was an LM308, which had sufficiently low input bias current to let me make a differentiator with a time constant of 10 seconds or so. The differentiator was to pick out small changes (0.3%) in the loop impedance with very low rates of change (i.e. slow moving cars).
Our competition (Eagle Signals) used a resonant loop (like TI's chip) in an AGC'd oscillator circuit, and a partially charged NiCd cell for the long time constant. I avoided resonant/oscillator schemes because of fierce interaction between adjacent loops, and opted instead for a forced loop drive with the same master oscillator driving them all.
It would be fun to make a loop detector with this new chip. Interesting it's not mentioned as a possible application. Maybe it's not got enough input protection? A lighning strike near a detector loop can ruin your day!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
