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

μF to

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