All,
Does anyone know of a good reference on signal conditioning in automotive environments?
I need to construct some input circuits for a gasoline engine management system that I am working on. I have found some IC packages (and read their data sheets) and I have also found some very simple approaches using only a single resistor and a couple of capacitors (though this was used on a system that had an external Analog to Digital IC package, external that is with respect to the main processor).
In my case, I am using the Motorola MPC555 which has all of the AtoD stuf built in, but I don't want to run "raw" sensor output signals directly in to my MPC555 (for fear of melting it).
FYI - if you couldn't tell fom reading my request, I am not an electrical engineer nor do I develop embedded systems for a living. I spend my working hours as a medical imaging software jockey and I love cars.
Any suggestions? Thanks in advance for any pointers,
-Paul
