DA7217 single supply mode

Hi,

What DC voltages can be expected on the headphone outputs of the DA7217 in single supply mode? VDD = 1.8V

Kind regards,

Addendum:

Addendum:
we are planning to use the device in single supply mode, differential output.
I expected both the positive and negative headphone output pins to be biased around VDD/2 and swinging in opposite direction. Is this correct?
Is it possible to post a drawing of the voltage levels on both pos and neg outputs while outputting a sine wave?

Thanks,
pge

Hello pge,

Hello pge,

Both HP POS and HP NEG are centered around VMID (0.45*VDD) in single mode supply.
