I have a question. The circuit board has an external 5V input. The power line is too long, 3 meters. The voltage is too high when it is powered on. Should I use a TVS tube? Or add a filter capacitor?
Ask a simple but difficult to answer circuit question: What is the nature of the ground wire GND in the circuit?During the PCB Layout process, engineers will face different GND treatments.Why is this?
The signal is 0.1-1mv, and the temperature drift is very serious when amplified 1000 times. Can you recommend a good low temperature drift amplifier ? The requirements are low price, small temperature
