AD9171 design issue

Question asked by finn.guo@excelpoint.com.cn on Jul 14, 2018

Hello,

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.
