OPA380AIDGKT datasheet by Texas Instruments

OPA380AIDGKT Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA380AIDGKT?
  The maximum power dissipation of the OPA380AIDGKT 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 OPA380AIDGKT in a feedback loop?
  To ensure stability, it's essential to follow proper PCB layout practices, minimize parasitic capacitance, and use a compensation capacitor (if necessary) as recommended in the datasheet. Additionally, ensure that the feedback loop has a sufficient phase margin and gain margin.
• What is the recommended input and output capacitance for the OPA380AIDGKT?
  The recommended input capacitance is 10nF to 100nF, and the recommended output capacitance is 10nF to 1μF. However, the optimal capacitance values may vary depending on the specific application and layout.
• Can I use the OPA380AIDGKT as a comparator?
  While the OPA380AIDGKT can be used as a comparator, it's not the most suitable choice due to its relatively slow slew rate (2.5V/μs) and limited output current (±20mA). A dedicated comparator IC would be a better option for most applications.
• How do I protect the OPA380AIDGKT from ESD and overvoltage?
  To protect the OPA380AIDGKT from ESD and overvoltage, use TVS diodes or ESD protection devices on the input and output pins. Additionally, ensure that the power supply voltage does not exceed the recommended maximum rating of 5.5V.
