Hi ,
I am using DAC5681Z (DAC, 16-bit 1.0 GSPS) first time. our Analog output Voltage requirement is 0 to 2V. I am planning to use internal voltage reference of 1.2V.
I could see IOUTB1, IOUTB2 Compliance voltage can vary from AVDD–0.5 to AVDD+0.5. if AVDD=3.3 then Compliance voltage will be 3.8V to 2.8V.
So my Doubt is
1) By using 1:1 Balun, shall we get output is 3.8V to 2.8V or +0.5V to -0.5V?
2) Can i use any single transformer, which can directly provide 0 to 2V. If not please share opinion to get 0v to 2V output ?
3) Can we use any Opamp for same in range of 500Mhz output signal?
