DAC38J84EVM: How to get the full scale output?

Spencer Chen

Part Number: DAC38J84EVM

I enable the NOC function, set the Coarse DAC Gain to 10, the mixer gain disabled, I get 0.95V Vp-p, is it right? How can I get 1.5V Vp-p? Thanks!

Hi Spencer,

You may review the below app note and review the datasheet output compliance voltage recommendation

https://www.ti.com/lit/ug/slua647a/slua647a.pdf?ts=1626279986340&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDAC38J84

The output swing depends on the output load setup. Depending on your configuration of the load, it is possible that you already be exceeding the output compliance voltage recommendation. This is assuming you have a full-scale digital output (i.e. 0dBFS) tone at the output structure.
