DS1337+ datasheet by Maxim Integrated Products

DS1337+ Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the DS1337+ can handle?
  The DS1337+ can handle clock frequencies up to 32.768 kHz, which is the typical frequency for a 32.768 kHz crystal oscillator.
• How does the DS1337+ handle battery switchover during power failure?
  The DS1337+ has a built-in battery switchover circuit that automatically switches to the backup battery during power failure, ensuring continuous operation of the RTC.
• What is the accuracy of the DS1337+ RTC?
  The DS1337+ RTC has an accuracy of ±2 minutes per year at 25°C, making it suitable for most applications that require a high degree of timekeeping accuracy.
• Can the DS1337+ be used in low-power applications?
  Yes, the DS1337+ is designed for low-power applications, with a typical current consumption of 1.5 μA in battery-backed mode, making it suitable for battery-powered devices.
• How does the DS1337+ handle leap years and daylight saving time (DST)?
  The DS1337+ automatically accounts for leap years and can be programmed to handle DST, making it suitable for applications that require accurate timekeeping across different regions and time zones.
