OPA380AIDG4 datasheet by Texas Instruments

OPA380AIDG4 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA380AIDG4?
  The maximum power dissipation of the OPA380AIDG4 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 OPA380AIDG4 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, consider using a series resistor (Rs) to isolate the op-amp input from the capacitive load.
• What is the recommended input impedance for the OPA380AIDG4?
  The recommended input impedance for the OPA380AIDG4 is ≥1kΩ to ensure optimal performance and minimize input bias current effects.
• Can I use the OPA380AIDG4 as a comparator?
  While the OPA380AIDG4 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 like the LM339 or TLV7031 might be a better option for comparator applications.
• How do I handle ESD protection when using the OPA380AIDG4?
  To ensure ESD protection, follow proper handling and storage procedures, use an anti-static wrist strap or mat, and consider adding external ESD protection devices (e.g., TVS diodes) to the PCB design.
