LM339DR Frequently Asked Questions (FAQ)
-
The LM339DR can operate from -40°C to 125°C, but the output voltage swing and input offset voltage may vary with temperature.
-
To ensure stability, use a bypass capacitor (e.g., 10nF to 100nF) between the VCC pin and GND, and keep the input impedance low (e.g., <1kΩ) to prevent oscillations.
-
While the LM339DR is often referred to as an op-amp, it's actually a quad comparator. It's not suitable for linear amplifier applications due to its open-loop architecture and limited output swing.
-
The input impedance of the LM339DR is typically around 10MΩ, but it can vary depending on the input voltage and frequency.
-
The LM339DR has an open-drain output stage, so an external pull-up resistor is required to define the output voltage. Choose a pull-up resistor value based on the load current and voltage requirements.
