Overview of LM239QT

The LM239QT is a versatile quad differential comparator ideal for a wide range of applications. With its ability to operate on single-supply voltage ranging from 2V to 36V, this component is well-suited for various electronic projects. Its low input offset voltage of 3mV ensures accurate results in comparator applications, reducing potential errors that may arise. The quick response time of 1.3μs further enhances its efficiency, making it a reliable choice for time-sensitive projects. Additionally, the open-collector outputs provide flexibility for external connections, allowing for seamless integration with other components

Key Features

  • Wide single supply voltage range or dual supplies for all devices: +2 to +36 V or ±1 V to ±18 V
  • Very low supply current (1.1 mA) independent of supply voltage
  • Low input bias current: 25 nA typ
  • Low input offset current: ±5 nA typ
  • Low input offset voltage: ±1 mV typ
  • Input common-mode voltage range includes ground
  • Low output saturation voltage: 250 mV typ;(ISINK = 4 mA)
  • Differential input voltage range equal to the supply voltage
  • TTL, DTL, ECL, MOS, CMOS compatible outputs
