OPA2373AIDRCR datasheet by Texas Instruments

OPA2373AIDRCR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA2373AIDRCR?
  The maximum power dissipation of the OPA2373AIDRCR 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 OPA2373AIDRCR in a unity-gain configuration?
  To ensure stability in a unity-gain configuration, add a 10nF to 22nF capacitor in parallel with a 1kΩ to 2kΩ resistor between the output and the inverting input. This helps to compensate for the op-amp's phase shift and prevent oscillations.
• What is the recommended layout and routing for the OPA2373AIDRCR to minimize noise and EMI?
  To minimize noise and EMI, use a star-ground configuration, keep the input and output traces short and away from each other, and use a ground plane to shield the op-amp. Also, place the decoupling capacitors close to the op-amp's power pins.
• Can I use the OPA2373AIDRCR in a high-temperature environment?
  The OPA2373AIDRCR is specified to operate from -40°C to 125°C. However, the device's performance may degrade at higher temperatures. For high-temperature applications, consider using a more temperature-stable op-amp or implementing thermal management techniques.
• How do I choose the correct resistors and capacitors for the OPA2373AIDRCR's feedback network?
  Choose resistors with a tolerance of 1% or better, and capacitors with a tolerance of 10% or better. Select components with a temperature coefficient that matches the op-amp's temperature range. Also, consider the parasitic capacitance and inductance of the components when designing the feedback network.
