DS32KHz
4 of 8
The DS32KHz ICC and IBAT currents are specified with no output loads. Many RTC oscillator circuits are
designed to be used with a quartz crystal or resonator. Driving the oscillator circuit with the rail-to-rail
output of the DS32KHz may increase the ICC and IBAT currents significantly, and increase the current
consumption of the RTC as well. Figure 4 shows one recommended circuit that can be used to reduce the
current consumption of a DS32KHz and an RTC. The values of R1 and C1 will vary depending on the
RTC used. However, values of 1.0 M
and 100 pF are recommended as a starting point.
