T he Low Power Sleep Mode current is 2 mA typically when a 1 M
resistor is
not tied from REFOUT to AGND.
T he AD9830 is tested with a capacitive load of 50 pF. T he part can be operated
with higher capacitive loads, but the magnitude of the analog output will be attenu-
ated. For example, a 10 MHz output signal will be attenuated by 3 dB when the
load capacitance equals 250 pF.
