Very urgent!!! Dear experts, I have designed a 16-channel driver, but when compiling, it always prompts "has only one pin". I think it may be related to the bus, but I can't figure it out. Please give...
I would like to ask what simulation software can simulate the instantaneous voltage and current when only the capacitor and the power switch are charged.
The inductor receives the current change when ...
When AD8066 is connected to +6V, the output waveform is very good and ideal, but when it is connected to +12V power supply, the chip is directly burned out. Why? The power supply range of the chip is ...
I have been studying USB for two weeks, but I still feel that some concepts are not very clear. I think the key is that I don't know what the host actually does. I have tried to capture some USB devic...
