OPA373AID Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a layout that minimizes parasitic capacitance and inductance, keeps the input and output traces short and away from each other, and uses a solid ground plane to reduce noise and electromagnetic interference (EMI).
  • The gain resistors (Rf and Rg) should be chosen based on the desired gain and bandwidth of the amplifier. A higher gain requires smaller resistors, while a lower gain requires larger resistors. The datasheet provides a gain resistor calculator to help with the selection.
  • The maximum power dissipation of OPA373AID is 1.4W, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W. The actual power dissipation should be derated based on the ambient temperature and the device's operating conditions.
  • Yes, OPA373AID is specified to operate from -40°C to 125°C, making it suitable for high-temperature applications. However, the device's performance and reliability may degrade at extreme temperatures, and the maximum power dissipation should be derated accordingly.
  • To protect OPA373AID from EMI, use a shielded enclosure, keep the input and output traces short and away from each other, and use a common-mode choke or ferrite bead on the input lines. Additionally, use a low-pass filter or a shielding material to reduce radiated EMI.
