TLC2202ACD datasheet by Texas Instruments

TLC2202ACD Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of TLC2202ACD?
  The maximum power dissipation of TLC2202ACD is 670mW at 25°C free-air temperature, and it can be calculated using the formula: Pd = (TJ - TA) / θJA, where TJ is the junction temperature, TA is the ambient temperature, and θJA is the junction-to-ambient thermal resistance.
• How do I choose the correct gain resistor values for TLC2202ACD?
  The gain resistor values for TLC2202ACD can be chosen using the formula: Rf/Ri = (Vout/Vin) - 1, where Rf is the feedback resistor, Ri is the input resistor, Vout is the output voltage, and Vin is the input voltage. The values of Rf and Ri should be chosen to ensure stability and desired gain.
• What is the input impedance of TLC2202ACD?
  The input impedance of TLC2202ACD is typically around 10^12 ohms in parallel with 10pF, making it suitable for high-impedance sources.
• Can I use TLC2202ACD as a comparator?
  Yes, TLC2202ACD can be used as a comparator by connecting the inverting input to a reference voltage and the non-inverting input to the signal to be compared. However, it's essential to ensure that the input common-mode voltage range is within the specified limits.
• How do I reduce noise and oscillations in TLC2202ACD circuits?
  To reduce noise and oscillations in TLC2202ACD circuits, use proper PCB layout techniques, decouple the power supply with capacitors, and add a noise filter or a ferrite bead to the output. Additionally, ensure that the gain is set correctly, and the feedback network is properly designed.
