DAC81408: DAC81408 Register update

Hi AK,

Thank you for your reply.

What happens if I operate in single-end mode?

Is there a register map for single-end mode?

Hi,

These registers are meant to offset the DC imbalances in the differential pair.

Imbalances between the two differential signals result in common-mode and amplitude errors. The device incorporates an offset register that enables the user to introduce a voltage offset to the DACy channel of the DACx-y differential pair to compensate for a DC offset error between the two channels. The offset compensation gives a ±0.2%FSR adjustment window. The differential DAC data register must be rewritten after an update to the offset register.

It has no effect in single ended mode of operation, and there us no register map for single ended mode.

Hi,

I think that the register associated with differential mode your mentioned is below registers.

07h TOGGCONFIG0

08h TOGGCONFIG1

0Eh TRIGGER

21h OFFSET0

22h OFFSET1

And I think that other registers can be used for single-end mode.

Is this correct?

Hi,

Thank you for your reply.

I understand it.
