OPA548T-1 datasheet by Texas Instruments

OPA548T-1 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA548T-1?
  The maximum power dissipation of the OPA548T-1 is 2.5W, and it is dependent on the ambient temperature and the thermal resistance of the package.
• How do I ensure stability when using the OPA548T-1 in a feedback loop?
  To ensure stability, it is recommended to use a compensation capacitor between the output and the inverting input, and to minimize the phase shift in the feedback loop by using a low-ESR capacitor and a low-inductance layout.
• What is the recommended layout and grounding technique for the OPA548T-1?
  A star-grounding technique is recommended, where the grounds of the power supplies, the op-amp, and the signal sources are connected at a single point. Additionally, it is recommended to use a low-inductance layout and to minimize the length of the input and output traces.
• How do I protect the OPA548T-1 from overvoltage and ESD?
  It is recommended to use voltage clamps or transient voltage suppressors to protect the OPA548T-1 from overvoltage. Additionally, ESD protection can be achieved by using ESD-protection diodes or by following proper handling and storage procedures.
• What is the recommended operating temperature range for the OPA548T-1?
  The recommended operating temperature range for the OPA548T-1 is -40°C to 125°C, but it can be extended to -55°C to 150°C with derating.
