Comparator Function: A voltage comparator is a device that compares two input voltage signals and outputs a high or low voltage level depending on which input is greater.
Open-Collector Outputs: The LM339 features open-collector outputs. This means that the outputs can actively pull the voltage low but rely on external pull-up resistors to drive the voltage high.
Low Input Offset Voltage: The LM339 is known for having a low input offset voltage, which is the voltage difference between the inverting and non-inverting inputs required for the output to switch.
Wide Range of Supply Voltage: The LM339 is designed to operate over a wide range of supply voltages, typically from single-supply 2V to dual-supply ±18V.
Range: The LM339 has a wide common-mode input voltage range, making it suitable for various applications.
