I'm really amazed on how much options have appeared for the same operation thx all, and I have really learned from all of you, but...
...In my specific application, I must choose the closest possible to realtime AD option, and Melanies is a really great solution but it requires switching and waiting for a settling time for a succesfull digitalization.
My application is an IMU, which means sampling 8 A/D as fastest as possible, then applying kalman, then PID, while doing PWM, interrupt bidirectional communications, logic & communication to other PIC's. Probably I'm abusing my poor PIC, and from all tasks, analog conversion should be the priority as the rest of the processess are based on my movement sensors, to stabilize movement.
Is Amplifying all analog signals to 5v the best choice?
Is OpAmp the best choice to amplify them?
Really thx babies & guys.-
PD: I changed from PIC18F4431 to PIC18F4553, for faster speed (12 MIPS [48 MHz/4]), more A/D inputs (13 pins) and better A/D resolution (12 bit)
