REF198ESZ Frequently Asked Questions (FAQs)

  • The REF198ESZ is a sensitive device and requires careful layout and placement to minimize noise and ensure accurate performance. It's recommended to place the device close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC), and to use a solid ground plane to reduce noise. Additionally, it's essential to keep the device away from high-current or high-frequency signals.
  • The REF198ESZ has a relatively high output voltage noise of 100 μVpp. To minimize the impact of this noise, it's recommended to use a low-pass filter or a capacitor in parallel with the output to reduce the noise. Additionally, using a voltage regulator with a low noise output can also help to reduce the overall system noise.
  • The REF198ESZ has a recommended input voltage range of 4.5 V to 18 V. Operating the device outside of this range may affect its performance and accuracy. It's essential to ensure that the input voltage is within the recommended range to ensure accurate voltage reference output.
  • The REF198ESZ is a precision voltage reference device, and its long-term stability is critical. To ensure long-term stability, it's recommended to operate the device within the recommended temperature range, avoid exposing it to extreme temperatures, and minimize power cycling. Additionally, using a high-quality capacitor with low equivalent series resistance (ESR) can help to reduce noise and ensure stable operation.
  • The REF198ESZ is rated for operation up to 125°C, but its performance may degrade at high temperatures. If you need to operate the device in a high-temperature environment, it's recommended to derate the device's performance and consider using a thermally enhanced package or a heat sink to reduce the junction temperature.
