POWER-DOWN MODE
The AD5330/AD5331/AD5340/AD5341 have low power
consumption, dissipating only 0.35 mW with a 3 V supply and
0.7 mW with a 5 V supply. Power consumption can be further
reduced when the DAC is not in use by putting it into power-
down mode, which is selected by taking Pin PD low.
When the PD pin is high, the DAC works normally with a
typical power consumption of 140 μA at 5 V (115 μA at 3 V).
In power-down mode, however, the supply current falls to
200 nA at 5 V (80 nA at 3 V) when the DAC is powered down.
Not only does the supply current drop, but the output stage
is also internally switched from the output of the amplifier,
making it open-circuit. This has the advantage that the output
is three-state while the part is in power-down mode and provides
a defined input condition for whatever is connected to the
output of the DAC amplifier. The output stage is illustrated in

Figure 39. Output Stage During Power-Down
The bias generator, the output amplifier, the resistor string, and
all other associated linear circuitry are shut down when the
power-down mode is activated. However, the contents of the
registers are unaffected when in power-down. The time to exit
power-down is typically 2.5 μs for VDD = 5 V and 5 μs when
VDD = 3 V. This is the time from a rising edge on the PD pin to
when the output voltage deviates from its power-down voltage
(see
).
