POWER-SUPPLY SEQUENCE
The preferred power-up sequence is to ramp AV
DD
first, followed by DRV
DD
, including a simultaneous ramp of
AV
DD
and DRV
DD
. In the event that DRV
DD
ramps up first in the system, care must be taken to ensure that AV
DD
ramps up within 10 ms. Optionally, it is recommended to put a 2-k
resistor from REFP (pin 29) to AVDD as
shown in
Figure 28
. This helps to make the device more robust to power supply ramp-up timings.

POWER-DOWN
The device enters power-down in one of two ways: either by reducing the clock speed or by setting the PDN bit
throughout the serial programming interface. Using the reduced clock speed, power-down may be initiated for
clock frequency below 2 MSPS. The exact frequency at which the power down occurs varies from device to
device.

Figure 27. Using the THS4503 with the ADS5510
Figure 28.
Using the serial interface PDN bit to power down the device places the outputs in a high-impedance state and
only the internal reference remains on to reduce the power-up time. The power-down mode reduces power
dissipation to approximately 180 mW.
