OPA4387PWT Frequently Asked Questions (FAQs)

  • A good PCB layout for OPA4387PWT involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing decoupling capacitors close to the power pins. A 4-layer PCB with a dedicated analog ground plane is recommended.
  • 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, but may compromise bandwidth. TI provides a gain resistor calculator tool to help with this selection.
  • The maximum power dissipation of OPA4387PWT is dependent on the ambient temperature and the thermal resistance of the package. For the PWT package, the maximum power dissipation is approximately 1.4W at 25°C ambient temperature.
  • OPA4387PWT is specified to operate from -40°C to 125°C, but the device's performance may degrade at higher temperatures. It's essential to consider the thermal management and derate the power dissipation accordingly to ensure reliable operation.
  • To protect OPA4387PWT from EMI, use a shielded enclosure, keep the input and output traces short, and use a common-mode choke or ferrite bead on the input lines. Additionally, consider using a low-pass filter or a shielding material around the device.
