OPA847ID Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the OPA847ID is 1.4W, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 90°C/W.
  • 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 good starting point is 10-22pF.
  • To minimize noise and EMI, it's recommended to use a star-ground configuration, keep the input and output traces short and away from each other, and use a ground plane to shield the device. Additionally, decouple the power supplies with 10uF and 100nF capacitors.
  • While the OPA847ID can be used as a comparator, it's not the most suitable device for this application. The OPA847ID is an op-amp optimized for high-speed and low-noise applications, and its output stage is not designed for high-current drive. For comparator applications, a dedicated comparator IC like the LM339 or TLV7031 is recommended.
  • To protect the OPA847ID from overvoltage and ESD damage, it's recommended to use a voltage clamp or a transient voltage suppressor (TVS) diode at the input pins. Additionally, use ESD protection devices like the TPD1E10B26 or the IP4232CZ6 at the input and output pins.
