OPA445AU Frequently Asked Questions (FAQs)

  • TI recommends using a 10uF ceramic capacitor in parallel with a 100nF ceramic capacitor, placed as close as possible to the power pins, to ensure stable operation.
  • To ensure stability in a unity-gain configuration, TI recommends adding a 10-20 ohm resistor in series with the output, and a 10-100pF capacitor in parallel with the feedback resistor.
  • The OPA445AU can drive up to 1nF of capacitive load, but it's recommended to limit the capacitive load to 100pF or less to ensure stability.
  • The OPA445AU is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the device's specifications according to the temperature derating curve in the datasheet.
  • To reduce noise and EMI, use a ground plane, keep signal traces short and away from noise sources, use shielding, and consider adding a common-mode choke or ferrite bead to the power supply lines.
