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

not used. Make sure to allow time for the reference to

μF to
reference typically requires 15ms. After the reference

μF, as shown. The I/O and digital supplies (IOVDD
has stabilized, allow at least 100 conversions for the

μF capacitors is needed on the main supply
bus, though each supply pin must still be bypassed
