TL084BCD datasheet by Texas Instruments

TL084BCD Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the TL084BCD?
  The maximum power dissipation of the TL084BCD is 1.4W, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (RθJA) of 90°C/W.
• Can I use the TL084BCD in a high-temperature environment?
  While the TL084BCD is rated for operation up to 70°C, it's not recommended for use in high-temperature environments above 85°C. For high-temperature applications, consider using a more suitable op-amp like the TLV084 or OPAx084.
• How do I ensure stability when using the TL084BCD in a unity-gain buffer configuration?
  To ensure stability in a unity-gain buffer configuration, add a 10-22nF capacitor between the output and the inverting input (pin 2) to prevent oscillations. This is especially important when using the TL084BCD with capacitive loads.
• What is the recommended layout and routing for the TL084BCD to minimize noise and oscillations?
  To minimize noise and oscillations, use a star-ground configuration, keep the input and output traces short and symmetrical, and avoid running signal traces near the power supply lines. Also, use a 0.1uF decoupling capacitor between the power supply pins (VCC and GND) to reduce noise.
• Can I use the TL084BCD as a comparator?
  While the TL084BCD can be used as a comparator, it's not the best choice due to its relatively slow slew rate (0.5V/us) and limited bandwidth (3MHz). For comparator applications, consider using a dedicated comparator like the LM339 or TLV7031.
