At $100 to read 12 TCs as well or better than any other option on the market it’s already priced at less than 10% of what any other option would cost and a great value. A 12 TC conditioner using the AD595 will likely add $300 all in. Still a very good value I think for people who need TCs and a n...

The digital may be less prone to stray RF, and other such analog noise(s). So it may be a bit more robust. The TC wires are running all though the engine bay analog, the I/O board should be away form that. I say don't bother with the digital chip for 5554 hardware and will try it and see what we ge...

Then why are we even talking about it?

The problem on a simple threshold plus a window is that the integrator which is attached after the HW/SW filter set also integrates noise or other stuff. It is essential to have an idea how my raw signal looks like. Human can see if something is going wrong but computer can't. If the Phytec PCM028 ...

Like living in the nothing plays with anything else without finding 1/2 dozen other things....no thanks. I'm a big fan of plug and play

To make knock detection available on a DIY device the trace data should be accessible by serial port or something similar. Not everyone has got a scope to do this and for saving a trace signal you need a expensive scope. As proposed by Dan the waveform should be sampled by the MCU itself for this r...

I think there are 2 groups who will want TCs. The first group is the turbo crowd. In this application 4 hz is plenty fast as it takes quite some time to burn a turbine. For this group 1 TC would cover over 95% of the users and 2 would get you 2 99.9%. I would see the TC signal triggering a warning l...

Got it. Thank you!

Looks like the two above mentioned chips are basically the chips that every one uses. As mentioned above, the AD chip is fast, and the max chip is digital. How about I draw it up with both, but we plan for the MAX chip to be the primary one. That way if someone wants a faster response, or is trying...

I'm sure the bandwidth of the analog part is much higher. Of course that may be moot depending how often the processor samples it. But if 4Hz will work, then the Maxim may become an option, especially if other parameters are taken into account. Temps don't change very fast so4 hz would be ok I thin...
