Just want to ask the AD9171 design issue as below:
1. Datashee page 56 showed below info, if can help to explain the following formula in detail:
The ac differential current measured at DACx+ and DACx− is as follows:
IAC_DIFF (mA) = DACCODE/DACCODEMAX × IOUTFS × RINT(RLOAD + RINT)
where: DACCODE = 0 to 65,535 (decimal).
RLOAD is the load impedance seen on DACx+ and DACx−.
2. How to calculate the AD9171 output power?
Thanks a lot.
