Hallo,

i want to have an ADC to get 0-3.3V output voltage and 0-5V input voltage.
(Some adc has Vdrv pin, which decides output voltage, but some of them dont have this.)
If i use an voltage divider at the output of ADC, to get 3.3 from 5V. would my signal still be accurate, is it logical to use voltage divider after ADC?

best regards
 

Hi,

?? Confusing..

Please be more descriptive. And/or us a schematic to explain what you want to achieve.
Give device types and datasheets and documents you refer to.

****

An ADC has analog input and digital output

So you talk about 3V3 digital logic level outputs?

And 0..5V analog full scale input voltage range?
(This could be easily adjusted with a 2 resistor voltage divider)
