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 AD5724/AD5734/AD5754. The power control register options are shown in Table 26 and Table 27.

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 upon 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 upon 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 upon 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 upon detection of an overcurrent, and PUD is cleared to reflect this.
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.
