OPA2691IDR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common-mode choke or a ferrite bead to filter out high-frequency noise.
  • To ensure stability, it's recommended to use a compensation capacitor (Cc) between the output and the inverting input pins. The value of Cc depends on the gain and bandwidth requirements, but a typical value is around 10-22pF. Additionally, it's recommended to use a low-ESR capacitor for the power supply decoupling.
  • The OPA2691IDR can drive a maximum capacitive load of 1nF. Exceeding this limit may cause oscillations or instability. If a larger capacitive load is required, it's recommended to use a buffer stage or a dedicated line driver.
  • To protect OPA2691IDR from overvoltage, it's recommended to use a voltage clamp or a transient voltage suppressor (TVS) diode at the input pins. For ESD protection, it's recommended to use a TVS diode or an ESD protection device at the input pins, and to follow proper ESD handling procedures during assembly and testing.
  • The OPA2691IDR has a thermal derating of 13.9mW/°C above 25°C. This means that the maximum power dissipation decreases by 13.9mW for every degree Celsius above 25°C. It's recommended to ensure good thermal conduction and to use a heat sink if necessary.
