OPA704NA/250 datasheet by Texas Instruments

OPA704NA/250 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of OPA704NA/250?
  A good PCB layout for OPA704NA/250 involves keeping the input and output traces short and away from each other, using a ground plane, and placing decoupling capacitors close to the power pins.
• How do I ensure stability when using OPA704NA/250 in a gain configuration?
  To ensure stability, use a gain resistor (Rg) that is less than or equal to 1 kΩ, and a feedback capacitor (Cf) that is greater than or equal to 10 pF. Also, ensure that the output impedance of the previous stage is less than or equal to 1 kΩ.
• What is the maximum power dissipation of OPA704NA/250?
  The maximum power dissipation of OPA704NA/250 is 670 mW. Exceeding this limit can cause the device to overheat and potentially fail.
• Can I use OPA704NA/250 in a high-temperature environment?
  While OPA704NA/250 is rated for operation up to 125°C, it's recommended to derate the power dissipation by 50% for every 10°C above 85°C to ensure reliable operation.
• How do I protect OPA704NA/250 from electromagnetic interference (EMI)?
  Use a shielded enclosure, keep the input and output traces away from each other, and use a common-mode choke or ferrite bead on the input lines to reduce EMI susceptibility.
