Multibandwidth System
Some applications may require multiple AD7716’s with differ-
ent bandwidths programmed to each device. The best way to
accomplish this is shown in Figure 12. The master mode inter-
face is used for this example but the slave mode may also be
used. The example shows an 8-channel system with Device #0
in the system programmed for a 292 Hz cutoff frequency and
Device #1 programmed for a 146 Hz cutoff frequency.

The resultant output signals are also shown. Since Device #0
has a higher bandwidth it will also have a higher update rate.
The receiving processor will be getting samples from this device
at twice the rate of Device #1.
