DS32kHz
POWER SUPPLY CONNECTIONS
Figure 1.0 shows how the DS32kHz should be connected when using two power supplies. V
should be
CC
between 4.5 and 5.5 volts while V
should be between 2.7 and 3.3 volts. Figure 2.0 shows how the
BAT
DS32kHz can be used when only a single supply system is available. V
should be grounded and V
CC
BAT
should then be held between 2.7 and 5.5 volts. The V
pin should be connected directly to a battery
BAT
using no external components.

Figure 4.0
Figure 3.0 illustrates how a standard 32.768kHz crystal and the DS32kHz should be connected to address
the interchangeable option. Using this connection scheme and the recommended layout provides a
solution, which requires no hardware modifications. Only one device should be used at a time and both
layouts should be located very close together if the recommended layout is not used.
