See Figure 11. T o reduce the wake-up time at low power supplies and low temperature, the use of an external reference is suggested.

Measured with the digital inputs static and equal to 0 V or DVDD.

T he Low Power Sleep Mode current is typically 2 mA when a 1 M
resistor is not tied between REFOUT and AGND.
T he AD9831 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 5 MHz output signal will be attenuated by 3 dB when the load capacitance equals 85 pF.
