Hello, Can you provide me with the DAC8830 1/F noise specifications?

The data sheet only states "Low Noise: 10 nV/√Hz"

Howdy Louis,

Welcome to the E2E forums! As you stated, the datasheet does displays a typical output noise value of 10 nV/√Hz at room temp. I'll check to see if we have any other published data that you may find helpful. Aside from the 1/F noise specifications, are there any other parameters or information that you may be interested in?

I'll update this post as I find any additional information.

Best Regards,

Matt

Hello Matt,

Knowing the 1/F corner frequency would be nice too.

Louis,

One thing I have overlooked is the fact that the DAC8830 is an un-buffered R2R DAC. As such, thermal noise will be the predominant noise in the device. A typical thermal noise rating of 10 nV/√H is specified in the datasheet.

Best Regards,
Matt
