Hi, I am going to change the voltage reference(2.048V) of my DAC(mcp4922) from ISL21080 to REF3120.I looked at the datasheet and it seems good enough for my purpose.Note that the DAC voltage ref input is unbuffered.Is there any problem using this v.ref.? Here is the datasheet please have a look at it. |

Your link is brocken, but what you do is look at the output current of the voltage reference in it's datasheet and then look up the input current to the voltage reference pin in the datasheet for the DAC. |

If that is your attitude good luck learninig electronics. Maybe you want to try lego bricks where everything is made for each other and nothing can go wrong! |
