OPA3355EA/2K5 datasheet by Texas Instruments

OPA3355EA/2K5 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of OPA3355EA/2K5?
  A good PCB layout for OPA3355EA/2K5 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 and application notes.
• How do I choose the right gain resistors for my application?
  The gain resistors (Rf and Rg) should be chosen based on the desired gain and bandwidth of the amplifier. TI provides a gain resistor calculator tool and application notes to help with this selection.
• What is the maximum power dissipation of OPA3355EA/2K5?
  The maximum power dissipation of OPA3355EA/2K5 is 1.4W, which is limited by the package thermal resistance and the ambient temperature. Engineers should ensure that the device is properly heat-sinked and that the power supply voltage and current are within the recommended limits.
• Can I use OPA3355EA/2K5 as a unity-gain buffer?
  Yes, OPA3355EA/2K5 can be used as a unity-gain buffer by connecting the output to the inverting input and using a gain resistor (Rf) of 0 ohms. However, this configuration may not provide the best noise performance, and engineers should consider the input impedance and noise requirements of their application.
• How do I handle EMI and RFI in my OPA3355EA/2K5 design?
  To minimize EMI and RFI in OPA3355EA/2K5 designs, engineers should use proper shielding, grounding, and filtering techniques. TI provides application notes and design guides on EMI and RFI mitigation for analog circuits.
