TL084ACD datasheet by STMicroelectronics

TL084ACD Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the TL084ACD?
  The maximum power dissipation of the TL084ACD is dependent on the package type and ambient temperature. For the DIP package, it is typically around 500mW at 25°C. However, it's essential to calculate the power dissipation based on the specific application and thermal conditions.
• Can I use the TL084ACD as a comparator?
  While the TL084ACD can be used as a comparator, it's not the most suitable choice. The TL084ACD is an op-amp designed for linear applications, and its output stage is not optimized for high-speed switching. For comparator applications, it's recommended to use a dedicated comparator IC, such as the LM339 or TLV7031.
• What is the input impedance of the TL084ACD?
  The input impedance of the TL084ACD is typically around 2MΩ, but it can vary depending on the specific application and frequency of operation. It's essential to consider the input impedance when designing the circuit to ensure proper signal attenuation and noise rejection.
• Can I use the TL084ACD in a high-temperature environment?
  The TL084ACD is rated for operation up to 70°C, but it's essential to consider the derating of the device's parameters at higher temperatures. For high-temperature applications, it's recommended to use a more suitable op-amp, such as the TLV247x or OPAx197, which are designed for high-temperature operation.
• What is the slew rate of the TL084ACD?
  The slew rate of the TL084ACD is typically around 13V/μs, which is relatively slow compared to modern op-amps. This can affect the device's ability to handle high-frequency signals and may lead to distortion and ringing in the output signal.
