TYPICAL CONNECTION DIAGRAM
Figure 41 shows the typical connection diagram for the
AD7609. There are four AVCC supply pins on the part that
can be tied together and decoupled using a 100 nF capacitor at
each supply pin and a 10 F capacitor at the supply source. The
AD7609 can operate with the internal reference or an externally
applied reference. In this configuration, the AD7609 is config-
ured to operate with the internal reference. When using a single
AD7609 device on the board, the REFIN/REFOUT pin should
be decoupled with a 10 F capacitor. In an application with
multiple AD7609 devices, see the Internal/External Reference
section. The REFCAPA and REFCAPB pins are shorted together
and decoupled with a 10 F ceramic capacitor.
The VDRIVE supply is connected to the same supply as the pro-
cessor. The voltage on VDRIVE controls the voltage value of the
output logic signals. For layout, decoupling, and grounding
hints, see the Layout Guidelines section.
After supplies are applied to the AD7609, a reset should be
applied to the AD7609 to ensure that it is configured for the
correct mode of operation.
POWER-DOWN MODES
There are two power-down modes available on the AD7609.
The STBY pin controls whether the AD7609 is in normal mode
or one of the two power-down modes. The two power-down
modes available are standby mode and shutdown mode. The
power-down mode is selected through the state of the RANGE
pin when the STBY pin is low. Table 8 shows the configurations
required to choose the desired power-down mode. When the
AD7609 is placed in standby mode, the current consumption is
8 mA maximum and power-up time is approximately 100 s
because the capacitor on the REFCAPA/REFCAPB pins must
charge up. In standby mode, the on-chip reference and
regulators remain powered up and the amplifiers and ADC core
are powered down. When the AD7609 is placed in shutdown
mode, the current consumption is 11 A maximum and power
up time is about 13 ms. In shutdown mode, all circuitry
is powered down. When the AD7609 is powered up from
shutdown mode, a reset signal must be applied to the AD7609
after the required power-up time has elapsed.
