We need a single channel a2d in the range of +-10V with resolution of 20microVolts
i looked at the AD7732 and its evaluation kit. will this product do the job?
if so, i going to connect it to a linux PC where can I find the command set for the RS232 serial port?
Hi Oded Godsi,
The AD7732 will be a good choice base from the specification that you describe. I have also filters other parts that may help with your application. By the way, what is the specific application you intend to use the part? If you want to search more ADCs that is fit to your application, you may visit the ADI website and do a parametric search and filter the search base from your own specification. Please refer to the link. Selection Table for All A/D Converters
thanks for your answer,
i have one more question:
i would like to also purchase the evaluation board for it,
but i need to sure that my Linux PC would be able to "talk" with this board through the RS232 serial port.
is there a list of the commands set ?
We have not try running the evaluation board on Linux OS, so we are not really sure if it will work. But there is a generic AD7734 generic driver if you wanted to develop your own software. Kindly refer to the link AD7734 - Microcontroller No-OS Driver [Analog Devices Wiki] .
Again thanks for your answers it was really helpful.
So a managed to connect the evaluation board to my Linux PC and it works most of the time...
because there are some communication problems.
I think it is because the board is located about 10 meters from the PC.
Is there a possibility to change the Baud Rate of the evaluation board from 38400 to 9600?
Or is there another way to get over this problems
