POWER DOWN (PD)
POWER SUPPLIES
When not in use, the ADS1601 can be powered down
Three supplies are used on the ADS1601: analog
by taking the PD pin low. All circuitry is shut down,
(AVDD), digital (DVDD) and digital I/O (IOVDD). Each
including the voltage reference. To minimize the
supply must be suitably bypassed to achieve the best
digital current during power down, stop the clock
performance. It is recommended that a 1
μF and
signal supplied to the CLK input. There is an internal
0.1
μF ceramic capacitor be placed as close to each
pull-up resistor of 170k
on the PD pin, but it is
supply pin as possible. Connect each supply-pin
recommended that this pin be connected to IOVDD if
bypass capacitor to the associated ground, as shown
not used. Make sure to allow time for the reference to

start up after exiting power-down mode. The internal
bypassed with a bank of capacitors from 47
μF to
reference typically requires 15ms. After the reference
0.1
μF, as shown. The I/O and digital supplies (IOVDD
has stabilized, allow at least 100 conversions for the
and DVDD) can be connected together when using
modulator and digital filter to settle before retrieving
the same voltage. In this case, only one bank of 47

μF capacitors is needed on the main supply
bus, though each supply pin must still be bypassed
with a 1
μF and 0.1μF ceramic capacitor.
