Hi guys,
I'm going to fabricate my first PIC-like F28027 main board, where I'm going to drive a small motor using TI's DRV8832 and detect a precise voltage using also TI's ADS1100.
BUT before that, just a couple of quick questions:
1. I'm just wondering if it's necessary to put resistors and diodes in between the pins of the F28027 to the DRV8832? I'm caught between two outcomes if I don't put any; whether it might induce erratic behavior due to the motor's spikes OR if I do put diodes/resistors might it render the output current too low?
2. A similar question for the ADS1100; do I do the same?
Any other suggestions are also welcome
Thanks guys.
Here's the PCB design screenshot, will edit more but this is just for show:
