    High-speed signals follow the path of least inductance

    I agree that current flows via lower resistor path. But When it comes to high speed signal does it follow the same.??? Because what I think is reactance is directly proportional to either frequency or inductance , when frequency is high then reactance is high and so inductance will be low. Is...

    AD5290 can not reach exact 0 volt

    Hello, Thank you all for helping. Now we are able to get 27mV offset for 0x00 input code. We changed the 10k pot to 100k pot. Before it was 250mV for 10k pot at zero scale error.
