Dear Sir,

we are looking for a DAC converter which output range would be 0~10mV.

Could you please give me some suggestion? wich DAC of TI is siutable for our application? Thanks.

Hi Passerby,

Can you share a little more information about your application?

How many steps do you need from 0 to 10 mV? (Resolution)

What kind of of accuracy do you need at each step?

What are you trying to control with such a small output range?

Dear Sir,

It is better to have each step 1mV.

this DAC output will connect to a high level controller for thermal indication, which indicator supports 0~10mV.

Thanks.

Dear Eugenio Mejia,
I am studying DAC9881. is it suitable for this appliation? Thanks.

Are you just trying to generate 11steps? 0 V, 1 mV, 2 mV... 9mV & 10mV? The DAC9881 it cannot do this on its own because of its large zero code error. It will require a negative supply and an external circuit to achieve this.

I would suggest taking a look at the DAC7311 and DAC8311 they have an extremely low zero code error of 0.2 mV typical and should also be able to meet your 1mV per step requirement.
