How can I calculate the Vout voltage of AD9833? I found the equation in the datasheet but some data are missing from the datasheet.
Here is the equation:
VOUT = VREF × 18 × RLOAD / RSET × (1 + (SIN (2π (FREQREG × fMCLK × t/2^28 + PHASEREG / 2^12))))
VREF? VDD or something else?
t? signal period or something else?
If I connect the DDS to the follower opamp and the RSET = 6.8kOhm then Vout = 0.65V? Because the RLOAD is very high and the Vout max = 0.65V if the RSET = 6.8kOhm because the datasheet said Voutmax = 0.65V if the RSET = 6.8kOhm.
Sorry My english is not perfect.
