CONTROL REGISTER
The control register is addressed by setting the three REG bits to 011. The value written to the address and data bits determines the
control function selected. The control register options are shown in Table 23 and Table 24.

Description
NOP
No operation instruction used in readback operations.
Clear
Addressing this function sets the DAC registers to the clear code and updates the outputs.
Load
Addressing this function updates the DAC registers and, consequently, the DAC outputs.
SDO Disable
Set by the user to disable the SDO output. Cleared by the user to enable the SDO output (default).
CLR Select
See Table 25 for a description of the CLR select operation.
Clamp Enable
Set by the user to enable the current-limit clamp. The channel does not power down upon detection of an overcurrent; the
current is clamped at 20 mA (default).
Cleared by the user to disable the current-limit clamp. The channel powers down upon detection of an overcurrent.
TSD Enable
Set by the user to enable the thermal shutdown feature. Cleared by the user to disable the thermal shutdown feature (default).

POWER CONTROL REGISTER
The power control register is addressed by setting the three REG bits to 010. This register allows the user to control and determine the
power and thermal status of the AD5722/AD5732/AD5752. The power control register options are shown in Table 26 and Table 27.

PUA
Table 27. Power Control Register Functions
Option
Description
PUA
DAC A power-up. When set, this bit places DAC A in normal operating mode. When cleared, this bit places DAC A in power-down
mode (default). After setting this bit to power DAC A, a power-up time of 10 μs is required. During this power-up time, the DAC
register should not be loaded to the DAC output (see the Load DAC (LDAC) section). If the clamp enable bit of the control register
is cleared, DAC A powers down automatically on detection of an overcurrent, and PUA is cleared to reflect this.
PUB
DAC B power-up. When set, this bit places DAC B in normal operating mode. When cleared, this bit places DAC B in power-down
mode (default). After setting this bit to power DAC B, a power-up time of 10 μs is required. During this power-up time, the DAC
register should not be loaded to the DAC output (see the Load DAC (LDAC) section). If the clamp enable bit of the control register
is cleared, DAC B powers down automatically on detection of an overcurrent, and PUB is cleared to reflect this.
TSD
Thermal shutdown alert (read-only bit). In the event of an overtemperature situation, both DACs are powered down and this bit is set.
OCA
DAC A overcurrent alert (read-only bit). In the event of an overcurrent situation on DAC A, this bit is set.
OCB
DAC B overcurrent alert (read-only bit). In the event of an overcurrent situation on DAC B, this bit is set.
