I am making a wheel encoder out of a Hall Effect sensor with magnets in a concentric circle on the wheel. The Hall effect sensor is on a 2-layer 9x5mm pcb. I usually fill in the layers by drawing a ...
I am planning to do a high current (200A+) PWM in a PCB and I am afraid the PCB traces inductances will be a huge problem...so I have some questions: 1- How may calculate the trace inductance? 2- As ...
It's on pin 14, which is the master clock input (MCLK) of a WM8761: Low cost stereo DAC. I'm guessing it's meant to act as a small inductor? But why would you want that on a clock input?
