OPA814DR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a layout with a solid ground plane, short traces, and minimal impedance mismatch. A 4-layer PCB with a dedicated analog ground plane is ideal. Keep the input and output traces separate and avoid crossing them over the power supply traces.
  • The gain resistors (Rf and Rg) should be chosen based on the desired gain and bandwidth. A higher gain requires smaller resistors, but may compromise bandwidth. Use the OPA814DR's gain-bandwidth product (GBP) to determine the maximum gain for a given bandwidth. TI's Op Amp Gain Calculator can also be used to simplify the process.
  • The maximum power dissipation for OPA814DR is 1.4W. To prevent overheating, ensure good thermal conductivity by using a heat sink or a thermally conductive PCB material. Keep the ambient temperature below 85°C and avoid high-power operation for extended periods.
  • Yes, OPA814DR can be used in a single-supply configuration. To do so, tie the negative input to a voltage divider that sets the input common-mode voltage to half the supply voltage. This allows the op amp to operate with a single supply voltage.
  • Use a low-pass filter (LPF) or a band-pass filter (BPF) to filter out high-frequency noise. A simple RC filter can be used, or a more complex filter like a multiple-feedback (MFB) or a Sallen-Key filter can be designed using TI's FilterPro software.
