Figure 14 illustrates the System Connection Dia-
gram for the CS5505/6 using a single +5V
supply. Note that all supply pins are bypassed
with 0.1 µF capacitors and that the VD+ digital
supply is derived from the VA+ supply.
Figure 15 illustrates the CS5505/6 using dual
supplies of +5 and -5V.

Figure 16 illustrates the CS5505/6 using dual
supplies of +10V analog and +5V digital.
When using separate supplies for VA+ and
VD+, VA+ must be established first. VD+
should never become more positive than VA+
under any operating condition. Remember to in-
vestigate transient power-up conditions, when
one power supply may have a faster rise time.
