DS1687-3+ datasheet by Maxim Integrated Products

DS1687-3+ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DS1687-3+?
  The recommended power-up sequence is to apply VCC first, followed by VEE. This ensures that the internal voltage regulators are powered up correctly.
• How do I ensure that the DS1687-3+ is in a low-power state during shutdown?
  To ensure low power consumption during shutdown, make sure to pull the SHDN pin low and ensure that the VCC and VEE pins are at 0V. This will put the device in a low-power state.
• What is the maximum capacitance value for the bypass capacitors on the VCC and VEE pins?
  The maximum capacitance value for the bypass capacitors on the VCC and VEE pins is 10uF. Exceeding this value may affect the device's performance and stability.
• How do I handle the thermal shutdown feature of the DS1687-3+?
  The thermal shutdown feature is enabled by default. If the device temperature exceeds 150°C, it will shut down. To handle this, ensure proper heat sinking and thermal management in your design.
• What is the recommended layout and routing for the DS1687-3+?
  To minimize noise and ensure proper operation, keep the analog and digital grounds separate, use a solid ground plane, and keep the input and output traces short and direct.
