AD5593R DAC setup question (gain = 2 mode)

Hello All,

 

I have two questions for DAC mode for AD5593R.

 

Q1) Is it OK for setup below?

VDD: 3.1V, VREF: 2.5V (Internal REF), 8-channels at the DAC mode

DAC VOUT = 2 x VREF (DAC range select bit = 1)

 

My customer got DAC VOUT Range is 0V to 2.9V. They understood and reduce the VOUT range, due to VDD = 3.1V.

But, is it any other problem for set the “2 x VREF Mode” at the VDD = 3.1V, instead of VDD = 5V?

 

Q2) Could you let me know what VOUT voltage value does saturate at the upper setup condition (VDD = 3.1V, Gain = 2)?

 

Best Regards,
