LM2902KVQDRG4 datasheet by Texas Instruments

LM2902KVQDRG4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the LM2902KVQDRG4?
  The recommended operating voltage range for the LM2902KVQDRG4 is 2.7V to 5.5V, although it can operate down to 2.3V with reduced performance.
• How do I ensure the LM2902KVQDRG4 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 1uF capacitor between the output pin and GND. Also, keep the input and output pins away from each other to minimize parasitic capacitance.
• What is the maximum output current that the LM2902KVQDRG4 can supply?
  The maximum output current that the LM2902KVQDRG4 can supply is 20mA per channel, although it's recommended to limit the output current to 10mA per channel for reliable operation.
• Can I use the LM2902KVQDRG4 as a comparator with an open-drain output?
  Yes, the LM2902KVQDRG4 can be used as a comparator with an open-drain output by connecting an external pull-up resistor to the output pin. However, this configuration may affect the output rise time and noise immunity.
• How do I handle the input common-mode voltage range for the LM2902KVQDRG4?
  The input common-mode voltage range for the LM2902KVQDRG4 is from VCC-1.5V to VCC+0.5V. Make sure to keep the input voltage within this range to ensure proper operation and prevent latch-up or oscillation.
