LM393DR2G Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the LM393DR2G is 2V to 36V, although it can operate down to 1.2V with reduced performance.
  • To ensure the input voltage stays within the common-mode range, use a voltage divider or an op-amp buffer to level-shift the input signal to be within 1.5V of the supply voltage.
  • The hysteresis pin (pin 5) is used to connect an external resistor and capacitor to create a hysteresis loop, which helps to prevent oscillations and improve noise immunity.
  • No, the LM393DR2G is a comparator, not an amplifier. It is designed to compare two input voltages and output a digital signal, not to amplify a signal.
  • The pull-up resistor value depends on the load current and the desired output voltage. A general rule of thumb is to choose a value between 1kΩ and 10kΩ, but consult the datasheet and application notes for specific guidance.
