DS2762AE+T&R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the DS2762AE+T&R to ensure optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10uF capacitor between VCC and GND, and a 100nF capacitor between VCC and AVCC.
• How do I ensure accurate temperature measurements with the DS2762AE+T&R?
  Use a thermocouple or a thermistor with a high accuracy rating. Ensure good thermal contact between the sensor and the device being measured. Use a low-pass filter to remove noise and averaging to improve accuracy.
• What is the maximum cable length for the 1-Wire interface of the DS2762AE+T&R?
  The maximum cable length for the 1-Wire interface is 100 meters, but it depends on the cable quality, noise environment, and data rate. Use a shielded cable and a repeater if necessary.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) in the DS2762AE+T&R?
  Use a capacitor between VCC and GND to filter out noise and ensure a clean power-on reset. Implement a power-up sequence to ensure a stable voltage before enabling the device. Use a voltage supervisor or a reset IC to handle brown-out conditions.
• What is the recommended clock frequency for the DS2762AE+T&R?
  The recommended clock frequency is 32.768 kHz, but it can operate up to 1 MHz. A higher clock frequency may reduce the accuracy of the temperature measurement.
