The DS32KHz I
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 I
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 1.0MW and 100pF are recommended as a starting point.
