I would like to measure the voltage with a voltage divider.
I would like to bias (offset, subtract) 5V with the ADR5045BKSZ-REEL7 from a 6-16V Voltage Source.
My current scheme is this:
I have calcuted that the Total current should be betwwen 75uA (6V Input) and 820uA (16v) Input. Max Voltage Output is about 3.5V, Minimum about 0.3V. (Spannungsteiler, belastet)
I have seen on another post that somebody made a similar circuit with a TL431 variable shunt regulator:
Do you agree that my solution should working?
Thank's very much for every input
I'm sorry. I mean ADC and not DAC. I would like to measure the voltage on the ADC from a stm32 so i need 0-3.3V Input level.
But i think the ADP7182 need also minimum current to operate? Anyway, I have seen that ADP7182 is more than double the price so it is too expensive.
Thank's very much
