DS32kHz
7 of 10
Figure 4 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.
The DS32kHz I
CC
and I
BAT
currents are specified with no output loads. Many RTC oscillator circuits use a quartz
crystal or resonator. Driving the oscillator circuit with the rail-to-rail output of the DS32kHz can increase the I
CC
and
I
BAT
currents significantly and increase the current consumption of the RTC as well. Figure 5 shows one circuit that
can be used to reduce the current consumption of a DS32kHz and an RTC. The values of R1 and C1 may vary
depending on the RTC used. However, values of 1.0M and 100pF are recommended as a starting point. R2 is
used to shift the input waveform to the proper level. The recommended value for R2 is 33k .

THIS SHOWS A CIRCUIT THAT CAN BE USED TO REDUCE
THE CURRENT CONSUMPTION OF A DS32kHz AND AN RTC.
THE STANDARD 32.768kHz CRYSTAL AND THE DS32kHz SHOULD BE CONNECTED TO ADDRESS THE
INTERCHANGEABLE OPTION.
