AD698AP Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VEE. This ensures that the internal circuitry is properly biased and prevents damage to the device.
  • To ensure accurate temperature measurement, it's essential to provide a stable voltage supply, minimize thermal gradients, and use a thermocouple with a high-quality junction. Additionally, calibrate the device according to the datasheet recommendations.
  • The maximum cable length for the thermocouple connection depends on the specific application and noise environment. As a general guideline, keep the cable length as short as possible (less than 10 feet) to minimize noise pickup and ensure accurate measurements.
  • No, the AD698AP is specifically designed for thermocouple temperature measurement. It's not compatible with thermistors or RTDs, which require different signal conditioning and amplification.
  • The AD698AP has an internal cold junction compensation circuit. However, for high-accuracy applications, it's recommended to use an external cold junction compensator or a thermocouple with an integrated cold junction compensator.
