Hi,
i have a BeagleBoard-X15 dev card with which a need to send a digital signal to a digital analog converter.
What integrated circuit could be the best to design the diagram for this purpose.
i have to generate 0 to 24Vdc
i saw this circui but the LM324N can output 10Vdc max as i can see in the diagram.
Thank you

 

Try running that circuit on 24V and change R3 to 680K. You may have to increase the supply to 25 or 26V to get 24V out, and 0V may not get quite there either. Running the output via a diode can help to remove the small residual output volts if the amp cannot quite get there.
Rail to rail OpAmps may be better.
But how accurate do you need the 0-24V?
You could toss that circuit together to play with and see if it works ok.

 

Thanks a lot.
i will try.

 

An LM324 operating off a 24V supply will not generate 24V out
because it is not a RRIO device. Either bump supply >> 24Vdc
or use a RRIO device.

The LM324 output is 2-3 V off the rail with a 10K ohm load, specs.

Note even RRIO devices are not RRIO when you start driving loads.
So pay attention to load specs when you do design.
