    [SOLVED] Is 1/2 Vss = floating

    Oh, Thanks. I did read that one, but for page 31, it didn't say that, then I forgot. Have a great holiday!

    [SOLVED] Is 1/2 Vss = floating

    Hi, An ADC datasheet said: if Pin4 is floating => DDR mode, if not floating => SDR mode, The schematic I saw connected this pin to voltage divider to get 1/2 Voltage supply, Is this ADC configured as DDR or SDR? floating means pin is not connected, but what 1/2 Vss Thanks.

    DC output current in a Datasheet

    Your video looks nice, so 1K resistor is good to limit current with reasonable brightness.

    DC output current in a Datasheet

    A STP16CP05 may be a good choice for LED driver.

    DC output current in a Datasheet

    I see, thanks you. I want to use this chip to drive 8LEDs which is 20mA each. This is the LED cube sch on the internet. How could it work? on ebay, most of LED i found rate at 20mA.

    DC output current in a Datasheet

    Hi, I have a question about DC output current in a datasheet. In this datasheet, page 7, it said DC output current is 35mA, Does it mean each output pin could output 35mA or total 35mA? Link to datasheet https://www.st.com/web/en/resource/technical/document/datasheet/CD00000339.pdf Thanks
