MAXIMUM DAC IOUT – mA
TPC 17. Effect of DAC maximum output current on
wideband (0 to 72 MHz) SFDR at three representa-
tive DAC output frequencies: 1.1 MHz, 40.1 MHz,
and 70.1 MHz. VS = 5 V, 180 MHz system clock (6
REFCLK multiplier disabled). Currents are set using
appropriate values of RSET.

INPUT FREQUENCY – MHz
TPC 18. Minimum p-p input signal needed to tog-
gle the AD9851 comparator output. Comparator
input is a sine wave compared with a fixed volt-
age threshold. Use this data in addition to sin(x)/x
rolloff and any filter losses to determine whether
adequate signal is being presented to the AD9851
comparator.
