OPA2345EA/250 Frequently Asked Questions (FAQs)

  • A good PCB layout for the OPA2345 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 device. TI provides a recommended layout in the datasheet.
  • The gain resistors (Rf and Rg) should be chosen based on the desired gain and bandwidth of the amplifier. A good starting point is to use the gain equation provided in the datasheet and adjust the values based on the specific application requirements.
  • The maximum power dissipation of the OPA2345 is dependent on the package type and ambient temperature. For the SOIC package, the maximum power dissipation is 670mW at 25°C. See the datasheet for more information.
  • Yes, the OPA2345 can be used as a unity-gain buffer by connecting the output directly to the inverting input and using a gain resistor (Rf) of 0Ω. However, this configuration may not provide the best noise performance.
  • To filter out noise and oscillations, use a capacitor in series with the gain resistor (Rf) and a capacitor in parallel with the feedback resistor (Rg). The values of these capacitors depend on the specific application and frequency range of interest.
