POWER-DOWN MODE
The ADS5270 has a power-down pin, PD. Pulling PD high
causes the devices to enter the power-down mode. In this
mode, the reference and clock circuitry as well as all the
channels are powered down. Device power consumption
drops to less than 100mW in this mode. Individual
channels can also be selectively powered down by
programming registers.
The ADS5270 also has an internal circuit that monitors the
state of stopped clocks. If ADCLK is stopped (or if it runs
at a speed < 3MHz), this monitoring circuit generates a
logic signal that puts the device in a power-down state. As
a result, the power consumption of the device goes to less
than 100mW when ADCLK is stopped. This circuit can
also be disabled using register options.
SUPPLY SEQUENCE
The following supply sequence is recommended for
powering up the device:
1.
2.
AVDD is powered up.
LVDD is powered up.
After the supplies have stabilized, it is required to give the
device an active RESET pulse. This results in all internal
registers getting reset to their default value of 0 (inactive).
Without RESET, it is possible that some registers might be
in their non-default state on power-up. This could cause
the device to malfunction.
LAYOUT OF PCB WITH
POWERPAD THERMALLY
ENHANCED PACKAGES
The ADS5270 is housed in an 80-lead PowerPAD
thermally enhanced package. To make optimum use of the
thermal efficiencies designed into the PowerPAD
package, the PCB must be designed with this technology
in mind. Please refer to SLMA004 PowerPAD brief
PowerPAD Made Easy
(refer to our web site at
www.ti.com), which addresses the specific considerations
required when integrating a PowerPAD package into a
PCB design. For more detailed information, including
thermal modeling and repair procedures, please see
SLMA002 technical brief
PowerPAD Thermally Enhanced
Package
