STM32H723 DACs

Repwoc · ‎2024-12-10

The datasheet for STM32H723VG (https://www.st.com/en/microcontrollers-microprocessors/stm32h723vg.html) states that the devices have 2 x 12 bit, 2-channel DACs.

However, in STM32CubeMX I see only one DAC listed (device = STM32H723VGT6).

Is this an error in the datasheet or an issue with STM32CubeMX? Or something else?

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.
