OPA355NA/250G4 datasheet by Texas Instruments

OPA355NA/250G4 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of OPA355NA/250G4?
  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.
• How do I ensure the OPA355NA/250G4 is stable in my application?
  To ensure stability, make sure to follow the recommended compensation network, and choose the correct gain resistors and capacitors. Also, ensure that the op-amp is not oscillating by checking the output waveform with an oscilloscope.
• What is the maximum power dissipation of OPA355NA/250G4?
  The maximum power dissipation of OPA355NA/250G4 is 1.4W. However, it's recommended to derate the power dissipation based on the ambient temperature and the thermal resistance of the package.
• Can I use OPA355NA/250G4 in a high-temperature environment?
  Yes, OPA355NA/250G4 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to consult the datasheet and application notes for more information.
• How do I protect OPA355NA/250G4 from ESD damage?
  To protect OPA355NA/250G4 from ESD damage, use ESD-safe handling and storage procedures, and consider adding ESD protection devices such as TVS diodes or ESD protection arrays to the PCB design.
