Do TI have DAC input from I2C and 4-20mA output?

 

Best Regards,

    Hi NT,

    The DAC8750 is a DAC + XTR device which will give you 4-20mA output. The only problem you may run into is that it is SPI. It is due out with a month or two. If interested, let me know and we can get you a preliminary data sheet.

    Regards,

    Hi Tony,

    My company is very much interested in the same. Can we a soft copy of the same?

    Hi NT,

     

    I am a bit late to this conversation, but I will use it as my practice run :)

     

    You may want to check out DAC161P997 - you can do a search on it at ti.com.

    It is a DAC built specifically for the isolated 4-20mA loop powered transmitters (Type-2 only).

     

    It has a SWIF interface, even more stingy on wiring than i2c -  just one wire needed to communicate with it, which is nice if you have to jump isolation boundary with your DAC input data.

     

    Cheers!
