Specification

Description

The LM339 is a quad voltage comparator IC (integrated circuit) that is widely used in analog and digital applications.

Here's a description of the LM339 IC:

Functionality: The LM339 is a quad voltage comparator, which means it contains four individual voltage comparator circuits within a single IC package.

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.

Applications:

The LM339 is used in a variety of applications such as voltage monitoring, level shifting, window comparators, waveform generators, pulse width modulators, and more.

Features

  • Wide supply voltage range
  • Very low supply current drain (0.8 mA) — independent of supply voltage
  • Low input biasing current: 25 nA
  • Low input offset current: ±5 nA
  • Offset voltage: ±3 mV
  • Input common-mode voltage range includes GND
  • Differential input voltage range equal to the power supply voltage
  • Low output saturation voltage: 250 mV at 4 mA
  • Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems

Applications

  • Oscillators
  • Voltage comparators
  • Peak detectors
  • Logic voltage translation
  • Power supervision
  • Industrial
  • Measuring instruments
  • Automotive
