Just got confussion regarding DAC output,
When I send 0, I have 1.5V - OK,
when I send 0x800000, I have 40mV - OK
but when I send 0x7FFFFF I have only 1.5V (same like 0), I should have something around 2.8V?

When I am sending FS sinusoid (0x7FFFFF, 0x800000) I have nice sine wave, 2Vpp, but this sine wave is not symetrical around 1.5V

Please advice what possibly I could make wrong.
