Hi, we are using a VQFN DAC7678 in a board. All channels work perfectly except the F one, which does not put voltages above 3.5V in his output. With the same code, the other channels put voltages over the entire range of the chip (0 to 5V).
In the F channel, codes until 3.5V works fine, but above that it's like there would be some kind of clamp... I have isolated the F-output to discard effects of the following analog parts but the problem persists
Please can you help in any way?
