Current sense amplifiers are amplifiers that detect current by measuring the voltage drop across a resistor in the current path. Current sense amplifiers output a voltage or current that is proportion...
OverviewQX6102 is a high-precision step-down high-power LED constant current driver chip with built-in NPN power transistor and self-powered function. It is suitable for non-isolated LED constant curr...
I want to do some wireless transmission recently, I want to transmit video signals wirelessly, but I haven't touched on this aspect yet. I want to hear everyone's opinions. What kind of film should I ...
In our common sense, the word technology often has two definitions. The first is the technology sealed in the laboratory. They are like flowers on the mountain top. Only a few people on the mountai...[Details]
In the actual project development process, it is common to encounter modifications to the hardware circuit, and then the modified part requires the modification of the driver. Thinking about the comi...[Details]
When Amazon launched its first

How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
