As for your HART DAC AD5410

Dear Sir/Madam,

I need for your good advice.

Our Customer is studying for HART modem product for his analog output board, so he asked following question.

Customer is thinking that AD5700+AD5410/20 is best way for his product due to built with a few components.

But on your datasheet show to select only 3 types 0~20mA, 0~24mA, and 4~20mA.

Question

When it is 12 bit ,and 4000 digit-instruction, then he want to output 20mA current.

So do you have the way to adjust for AD5410 in this case?

If no, do you have the another adjustable DAC(like AD5410)?

He needs the current output type DAC.

Thanks Kaos

  • Hi Kaos,

    Happy to help.

    I meant to add that the customer should look at the:

    AD5755-1 16-Bit current and voltage output DAC

    AD5757    16-Bit current only output DAC

    AD5737    12-Bit current only output DAC

    These products have a dedicated HART pin to directly couple the HART signal onto the current output. They also have the user adjustable gain and offset registers.

    Kind Regards,

    David
