TL074CDT datasheet by STMicroelectronics

TL074CDT Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the TL074CDT?
  The maximum power dissipation of the TL074CDT is 670mW, which is calculated based on the package thermal resistance and the maximum junction temperature.
• How do I ensure stability when using the TL074CDT in a unity-gain buffer configuration?
  To ensure stability, add a 10-22nF capacitor between the output and the inverting input to compensate for the internal pole. Additionally, ensure the layout is well-designed to minimize parasitic capacitance and inductance.
• What is the recommended supply voltage range for the TL074CDT?
  The recommended supply voltage range for the TL074CDT is ±2V to ±18V, with a maximum differential voltage of 36V. Operating outside this range may affect the op-amp's performance and reliability.
• Can I use the TL074CDT as a comparator?
  While the TL074CDT can be used as a comparator, it's not the most suitable choice due to its relatively slow slew rate (13V/μs) and limited bandwidth (3MHz). A dedicated comparator like the LM339 or TLV7031 would be a better option.
• How do I reduce noise and oscillations when using the TL074CDT in a high-gain configuration?
  To reduce noise and oscillations, use a low-pass filter at the input, add a 10-100Ω resistor in series with the input, and ensure the layout is well-designed to minimize parasitic capacitance and inductance. Additionally, consider using a higher bandwidth op-amp or a dedicated low-noise op-amp like the OP07 or OP27.
