INITIALIZING THE ADS1602
After the power supplies have stabilized, you must
initialize the ADS1602 by issuing a SYNC pulse as shown
in Figure 1. This operation needs only to be done once
after power-up and does not need to be performed when
exiting the Power-Down mode.
SYNCHRONIZING MULTIPLE ADS1602s
The SYNC input can be used to synchronize multiple
ADS1602s to provide simultaneous sampling. All devices
to be synchronized must use a common CLK input. With
the CLK inputs running, pulse SYNC on the falling edge of
CLK, as shown in Figure 46. Afterwards, the converters
will be converting synchronously with the FSO outputs
updating simultaneously. After synchronization, FSO is
held low until the digital filter has fully settled.

STEP RESPONSE
Figure 47 plots the normalized step response for an input
applied at t = 0. The x-axis units of time are conversions
cycles. It takes 51 cycles to fully settle; for f
