Part Number: DAC8551
Dear TI support team,
Comparing Figure 32 the curve zero voltage sink capability of the DAC8551 datasheet with DACs having a compareable output stage (see DAC80501 for example) , the valures presented in DAC8551 are factor 1000 or more better. Additionally if you have a close look on the curve for max. output voltage (2.7V - 10mV ) and you look on the y-axis, you have 2,7mV (instead of something in the range of 2.7V). Is there a typo? From my understanding "V" instead of "mV" as y-axis would give a more realistic picture.
Can you please support here?
PS: Same sitaution on DAC8551-Q1 for example
I agree. Being that the notation in Figure 32 for the DAC8551 indicates "DAC Loaded with FFFFh" at just above 2.5 on the Y-axis this must be in volts.
I will see about getting the datasheet owner to update the document.

You are correct. The y-axis is has a typo. The units should be volts. Given those units, the plot is much more reasonable.
Thanks for pointing this out!
In reply to Paul_Frost:
Hi Kevin, hi Paul,
thanks for your reply! Only to get closer to the full picture: I found this typo as well for the Figure 7. (Supply with 5V) and as i said, DAC8551-Q seems to have the same typo. So it may be the case, that this typo has a systematic reason.
