AD5061
Rev. B | Page 16 of 20
POWER-ON TO ZERO-SCALE OR MIDSCALE
The AD5061 contains a power-on reset circuit that controls the
output voltage during power-up. The DAC register is filled with
the zero-scale or midscale code and the output voltage is zero-
scale or midscale. It remains there until a valid write sequence is
made to the DAC. This is useful in applications where it is
important to know the state of the output of the DAC while it is
in the process of powering up.
SOFTWARE RESET
The device can be put into software reset by setting all bits in
the DAC register to 1; this includes writing 1s to Bit D23 to
Bit D16, which is not the normal mode of operation. Note that
the SYNC interrupt command cannot be performed if a
software reset command is started.
POWER-DOWN MODES
The AD5061 contains four separate modes of operation. These
modes are software-programmable by setting two bits (DB17
and DB16) in the control register. Table 6 shows how the state
of the bits corresponds to the mode of operation of the device.

1 kΩ to GND
When both bits are set to 0, the part works normally with its
normal power consumption. However, for the three power-
down modes, the supply current falls to less than 1 μA at 5 V
(265 nA at 3 V). Not only does the supply current fall, but the
output stage is also internally switched from the output of the
amplifier to a resistor network of known values. This has the
advantage that the output impedance of the part is known while
the part is in power-down mode. There are three different
options. The output is connected internally to GND through a
1 kΩ resistor or a 100 kΩ resistor, or it is left open-circuited
(3-state). The output stage is illustrated in Figure 39.

Figure 39. Output Stage During Power-Down
The bias generator, the DAC core and other associated linear
circuitry are all shut down when the power-down mode is
activated. However, the contents of the DAC register are
unaffected when in power-down. The time to exit power-down
is typically 2.5 μs for VDD = 5 V, and 5 μs for VDD = 3 V;
see Figure 19.
MICROPROCESSOR INTERFACING
AD5061-to-ADSP-2101/ADSP-2103 Interface
Figure 40 shows a serial interface between the AD5061 and the
ADSP-2101/ADSP-2103. The ADSP-2101/ADSP-2103 should
be set up to operate in the SPORT transmit alternate framing
mode. The ADSP-2101/ADSP-2103 SPORT is programmed
through the SPORT control register and should be configured
as follows: internal clock operation, active low framing, 16-bit
word length. Transmission is initiated by writing a word to the
Tx register after the SPORT has been enabled.
