LM2901PWG4 datasheet by Texas Instruments

LM2901PWG4 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LM2901PWG4?
  The LM2901PWG4 can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
• How do I ensure the LM2901PWG4 is stable and doesn't oscillate?
  To ensure stability, make sure to decouple the power supply pins (VCC and GND) with a 0.1uF ceramic capacitor, and use a minimum of 1kΩ resistor in series with the output pin to prevent oscillation.
• What is the recommended input voltage range for the LM2901PWG4?
  The recommended input voltage range for the LM2901PWG4 is 2V to 36V, but it can operate up to 40V with reduced performance.
• Can I use the LM2901PWG4 as a comparator with hysteresis?
  Yes, the LM2901PWG4 can be used as a comparator with hysteresis by adding an external resistor and capacitor network between the output and input pins to create a Schmitt trigger circuit.
• How do I choose the correct pull-up resistor value for the output pin?
  The pull-up resistor value depends on the load current and voltage requirements. A general rule of thumb is to use a pull-up resistor value between 1kΩ to 10kΩ, but it's recommended to consult the datasheet and application notes for specific guidance.
