OPA228U Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the OPA228U is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.
  • To ensure stability in a unity-gain configuration, it's recommended to add a capacitor (typically 10-22pF) between the output and the inverting input to compensate for the op-amp's internal capacitance.
  • To minimize noise and EMI, it's recommended to keep the input and output traces short and away from each other, use a ground plane, and decouple the power supply with a 0.1uF capacitor.
  • While the OPA228U can be used as a comparator, it's not recommended due to its relatively slow slew rate (2.5V/us) and limited output current (±30mA). A dedicated comparator IC would be a better choice for most applications.
  • The OPA228U has internal ESD protection, but it's still recommended to follow proper ESD handling procedures when handling the device, such as using an anti-static wrist strap and working on an ESD-protected surface.
