OPA703PA 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.
  • Choose gain resistors based on the desired gain, input impedance, and noise requirements. For a non-inverting amplifier, use the formula Rf/Rg = Gain - 1. For an inverting amplifier, use Rf/Rg = -Gain. Ensure the resistors are 1% or better tolerance and have a low temperature coefficient.
  • The OPA703PA can drive up to 1nF of capacitive load. However, it's recommended to limit the capacitive load to 500pF or less to ensure stability and prevent oscillations. Use a series resistor (Rs) to isolate the capacitive load and improve stability.
  • Use a voltage clamp or a transient voltage suppressor (TVS) to protect the OPA703PA from overvoltage. For ESD protection, use a diode array or a dedicated ESD protection device. Ensure the protection devices are rated for the maximum voltage and current of your application.
  • Use a 10uF to 22uF ceramic capacitor in parallel with a 100nF to 1uF ceramic capacitor, both placed as close as possible to the power supply pins. This will help filter out high-frequency noise and ensure a stable power supply.
