OPA453TA-1 datasheet by Texas Instruments

OPA453TA-1 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA453TA-1?
  The maximum power dissipation of the OPA453TA-1 is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.
• How do I ensure stability when using the OPA453TA-1 in a feedback loop?
  To ensure stability, it's essential to follow proper PCB layout practices, use a low-ESR capacitor for decoupling, and consider adding a compensation capacitor (e.g., 10-100pF) in parallel with the feedback resistor.
• What is the recommended operating voltage range for the OPA453TA-1?
  The OPA453TA-1 can operate from a single supply voltage of 2.7V to 36V, or from dual supplies of ±1.35V to ±18V. However, the recommended operating range is 5V to 30V for optimal performance.
• How do I protect the OPA453TA-1 from input overvoltage?
  To protect the OPA453TA-1 from input overvoltage, use input voltage limiting resistors and consider adding input clamping diodes (e.g., 1N4148) to prevent voltage exceeding the maximum rating of 42V.
• What is the typical slew rate of the OPA453TA-1?
  The typical slew rate of the OPA453TA-1 is 2.5V/μs, which is suitable for most audio and general-purpose applications.
