DS1834AS+T&R Frequently Asked Questions (FAQs)

  • The recommended layout and routing for the DS1834AS+T&R involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the device and the crystal oscillator. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane to reduce noise and EMI.
  • To ensure the accuracy of the temperature measurement, it's essential to calibrate the device, use a high-accuracy crystal oscillator, and minimize thermal gradients on the PCB. Additionally, the device should be mounted in a way that minimizes thermal coupling to other components, and the temperature sensor should be placed in a location that accurately represents the temperature of the system.
  • The maximum clock frequency that can be used with the DS1834AS+T&R is 100 kHz. However, the device can operate at frequencies up to 200 kHz, but with reduced accuracy and stability.
  • The POR and BOR features of the DS1834AS+T&R can be handled by using an external reset circuit or by using the device's internal reset circuitry. The internal reset circuitry can be enabled by connecting the RST pin to VCC, and the device will automatically reset when the power supply voltage falls below the brown-out threshold.
  • The recommended power supply decoupling for the DS1834AS+T&R involves using a 10 μF ceramic capacitor in parallel with a 100 nF ceramic capacitor, both connected between the VCC pin and the GND pin. This helps to filter out noise and reduce the impact of power supply variations on the device's performance.
