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 AD5724R/AD5734R/AD5754R. The power control register options are shown in Table 27 and Table 28.

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.
PUC
DAC C power-up. When set, this bit places DAC C in normal operating mode. When cleared, this bit places DAC C in power-down
mode (default). After setting this bit to power DAC C, 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 C powers down automatically on detection of an overcurrent, and PUC is cleared to reflect this.
PUD
DAC D power-up. When set, this bit places DAC D in normal operating mode. When cleared, this bit places DAC D in power-down
mode (default). After setting this bit to power DAC D, 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 D powers down automatically on detection of an overcurrent, and PUD is cleared to reflect this.
PUREF
Reference power-up. When set, this bit places the internal reference in normal operating mode. When cleared, this bit places the
internal reference in power-down mode (default).
TSD
Thermal shutdown alert. Read-only bit. In the event of an overtemperature situation, the four 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.
OCC
DAC C overcurrent alert. Read-only bit. In the event of an overcurrent situation on DAC C, this bit is set.
OCD
DAC D overcurrent alert. Read-only bit. In the event of an overcurrent situation on DAC D, this bit is set.
