Description

The LM339 includes four independent comparators with a low offset voltage, making it suitable for precision applications where accurate voltage comparison is crucial. Each comparator has an open-collector output, allowing for easy interfacing with various logic levels.

Features

  • Quad Configuration: Contains four independent comparators in a single package, allowing for space-efficient and versatile circuit designs.
  • Low Offset Voltage: Provides accurate voltage comparison with minimal offset errors.
  • Open-Collector Outputs: Allows the output to be connected to different logic levels and interfaces with pull-up resistors for digital logic compatibility.
  • Low Power Consumption: Designed to operate with minimal power, making it suitable for battery-operated and low-energy applications.
  • Wide Supply Voltage Range: Operates over a broad range of supply voltages, providing flexibility in circuit design.

Specifications

  • Input Offset Voltage: 2 mV (typical)
  • Input Offset Voltage Drift: 0.5 µV/°C (typical)
  • Input Bias Current: 50 nA (typical)
  • Propagation Delay: 300 ns (typical)
  • Common-Mode Rejection Ratio (CMRR): 100 dB (typical)
  • Power Supply Voltage: 2V to 36V (single supply) or ±1V to ±18V (dual supply)
  • Supply Current: 1 mA per comparator (typical)
  • Operating Temperature Range: 0°C to +70°C
  • Package: 14-pin DIP

Applications

  • Voltage Level Detectors: Used to monitor and respond to specific voltage thresholds in various electronic systems.
  • Zero-Crossing Detectors: Can detect when an AC signal crosses zero volts, useful in phase-locked loops and power control applications.
  • Overvoltage and Undervoltage Protection: Provides voltage monitoring to protect circuits from excessive or insufficient voltage conditions.
  • Pulse Width Modulation (PWM) Generation: Used in PWM circuits for motor control and other applications requiring precise voltage comparisons.
  • Signal Conditioning: Employed in circuits where multiple voltage levels need to be monitored and compared.
