I was looking foward to powering a small Integrated Circuit using only the power provided by the ethernet outlet of my room. Is that even possible? I've googled and I've found that the voltage that ...
I have a module with an ADC with a maximum input voltage of 2V. I would like to monitor the battery voltage of 15V with this input. I have successfully used a trimpot as a voltage divider to ...
I would like to add ADC functionality to a TI C6748 dev board. I need 16bit precision, but relatively low sample rate(~5K). Not finding any suitable daughter ADC card, I am considering the ...
I am looking at a MCP3008 datasheet and it says that it has a maximum current drain of 150uA, and a typical current drain of 100uA. I am building a voltage divider to knock down 96V to 3V. As this ...
I am trying to build a pH meter using the below circuit. I am trying to understand the function of Op Amp U1. As I understand it, the LM4140A-1.0 is a voltage reference outputting 1.024V, which is ...
I know what an Arduino's ADC generates a number with 10 bits of resolution (0 to 1023). How is this number generated? Is there a minimum and maximum voltage it will assign 0 and 1023 to, respectively? ...
