OPA2244EA/2K5 datasheet by Texas Instruments

OPA2244EA/2K5 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA2244EA/2K5?
  The maximum power dissipation of the OPA2244EA/2K5 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 OPA2244EA/2K5 in a feedback loop?
  To ensure stability, it's essential to follow proper PCB layout practices, use a low-ESR capacitor for decoupling, and avoid capacitive loads. Additionally, consider adding a small capacitor (e.g., 10pF to 100pF) in parallel with the feedback resistor to improve stability.
• What is the recommended operating voltage range for the OPA2244EA/2K5?
  The recommended operating voltage range for the OPA2244EA/2K5 is ±2.5V to ±18V. However, the device can operate with a single supply voltage from 5V to 36V.
• How do I handle ESD protection when working with the OPA2244EA/2K5?
  To prevent electrostatic discharge (ESD) damage, use proper handling and storage procedures, such as using an anti-static wrist strap, mat, or storage container. Additionally, consider adding ESD protection devices, like TVS diodes, to your circuit design.
• What is the typical input bias current of the OPA2244EA/2K5?
  The typical input bias current of the OPA2244EA/2K5 is 10pA, which is relatively low and suitable for high-impedance applications.
