TLC27M9CDR datasheet by Texas Instruments

TLC27M9CDR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of TLC27M9CDR?
  The maximum power dissipation of TLC27M9CDR is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and thermal resistance (RθJA) of 75°C/W.
• How do I ensure stability in the TLC27M9CDR op-amp?
  To ensure stability in the TLC27M9CDR op-amp, it is recommended to use a compensation capacitor (CC) between the output and the inverting input pins. The value of CC depends on the gain and bandwidth requirements of the application.
• What is the input impedance of TLC27M9CDR?
  The input impedance of TLC27M9CDR is typically around 10^12 ohms, which is very high and makes it suitable for high-impedance sources.
• Can I use TLC27M9CDR as a comparator?
  Yes, TLC27M9CDR can be used as a comparator, but it is not recommended due to its slow slew rate (0.3V/μs) and limited bandwidth (1.5MHz). Texas Instruments recommends using a dedicated comparator like the LM339 or LM2901 for comparator applications.
• How do I reduce noise in TLC27M9CDR circuits?
  To reduce noise in TLC27M9CDR circuits, use proper PCB layout techniques, such as separating analog and digital grounds, using bypass capacitors, and minimizing trace lengths. Additionally, consider using a noise-reducing capacitor (e.g., 10nF) between the inverting input and ground.
