#123155 - 2.56v reference voltage diode for ADC0838 |
Question 1:
I have done some searching but i only found 2.5V being the closest value which is the LM336 diode. Is there any more accurate reference voltage diode, in my case 2.56V which is used for the Vref pin of my ADC. I wanted to avoid using potentiometer as the voltage divider if possible. So please let me know the model number if there is any! Thank you very much! Question 2: How many minimum number of pin necessary to operate the ADC to be able to accept analogue input and output it to MCU? So far, i have found out that DI, DO, CLK, and CS, Vref, AGND as well as the corresponding Channel input is needed. Is there anymore necessary pin that is needed? Also, what is diffrence between the AGND and DGND pin? Question 3: Is there a minimum detectable current required for the analogue input of ADC? If yes, how much? That is all i need to know for now. Thank you very much! |
