AD5330/AD5331/AD5340/AD5341  
The low data byte of the AD5341 consists of data bits 0 to 7 at  
data inputs DB0 to DB7, while the high byte consists of data  
bits 8 to 11 at data inputs DB0 to DB3 as shown in Figure 29.  
DB4 to DB7 are ignored during a high-byte write, but they may  
be used for data to set up the reference input as buffered/  
unbuffered, and buffer amplifier gain. See Figure 33.  
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 mak-  
ing it open-circuit. This has the advantage that the output is  
three-state while the part is in power-down mode and pro-  
vides a defined input condition for whatever is connected to  
the output of the DAC amplifier. The output stage is illus-  
trated in Figure 30.

POWER-ON RESET  
The AD5330/AD5331/AD5340/AD5341 are provided with a  
power-on reset function, so that they power up in a defined state.  
The power-on state is:

• Reference Input Unbuffered  
• 0 – VREF Output Range  
• Output Voltage Set to 0 V  
Figure 30. 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 Figure 22.  
Both input and DAC registers are filled with zeros and remain so  
until a valid write sequence is made to the device. This is  
particularly useful in applications where it is important to know  
the state of the DAC outputs while the device is powering up.  
POWER-DOWN MODE  
The AD5330/AD5331/AD5340/AD5341 have low power con-  
sumption, dissipating only 0.35 mW with a 3 V supply and  
0.7 mW with a 5 V supply. Power consumption can be further
