LT1013CD Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LT1013CD?
  The maximum power dissipation of the LT1013CD is 670mW, which is calculated based on the maximum junction temperature (150°C) and the thermal resistance (θJA) of the package.
• How do I ensure stability when using the LT1013CD in a unity-gain buffer configuration?
  To ensure stability, add a 10-22pF capacitor between the output and the inverting input, and a 1kΩ-2kΩ resistor in series with the feedback path. This helps to reduce ringing and oscillations.
• What is the recommended layout and routing for the LT1013CD to minimize noise and EMI?
  Keep the input and output traces short and away from each other, use a ground plane, and avoid running sensitive traces near the op-amp's power pins. Also, decouple the power supply with a 10uF capacitor and a 0.1uF capacitor in parallel.
• Can I use the LT1013CD as a comparator?
  While the LT1013CD can be used as a comparator, it's not the best choice due to its relatively slow slew rate (0.5V/us) and limited output current (±3mA). A dedicated comparator like the LM339 or LM2901 would be a better option.
• How do I handle the input bias current of the LT1013CD?
  The input bias current of the LT1013CD is typically 25nA, which can cause voltage offsets. To minimize this effect, use a high-impedance input source, add a bias current compensation resistor, or use a chopper-stabilized op-amp like the LTC1050.
