Hello,

STM32H7 has one DAC instance DAC1 with two output channels on DAC1_OUT1 / DAC1_OUT2.

From the reference manual:

OK thanks.  So it appears that the datasheets are misleading at best.  I suggest that they are updated to say "1 x 12 bit, 2 channel DAC".  Then there would be no ambiguity and no confusion.

I think it's something inherited from the first F1 family and it's "misuse of language".

Note it's the "Product overview" web page linked to above that states 2 x 12-bit, 2-channel DACs, not the datasheet.

I will escalate that internally to fix the web page.
