Analog Comparators Quad GP Differential

LM239D Information

Description

The Motorola LM239D is a quad differential comparator device that offers high performance and versatility for various applications. This component can operate with a wide single supply voltage range or dual supplies, making it suitable for systems requiring flexibility. With its extremely low supply current of only 1.1mA, regardless of the supply voltage, the LM239D conserves power while providing excellent performance. Key features include ultra-low input bias, offset current, and voltage, making it ideal for precision applications. The comparator also has a large differential input voltage range equal to the supply voltage and can be used with TTL, DTL, ECL, MOS, or CMOS devices. This product supports SOIC-14 packaging and is commercially graded for reliability.

Features

According to the product information, the features of the LM239D are:

  • 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

Package

The package type of LM239D is SOIC-14 (Small Outline Integrated Circuit - 14 pins).

Pinout

Based on the provided product information, I found that: The LM239D has a package type of SOIC-14, which means it has 14 pins. As for its function, according to the description, it is a "Quad differential comparator", indicating that it can compare multiple analog input signals and produce an output based on certain conditions.

Manufacturer

The manufacturer of the LM239D is Motorola Mobility LLC.

Applications

The LM239D quad differential comparator is a versatile device that can be used in various applications, including:

  • Data acquisition and conversion systems
  • Automatic test equipment (ATE)
  • Digital signal processing (DSP) systems
  • Analog-to-digital converters (ADCs) and digital-to-analog converters (DACs)

Its compatibility with TTL, DTL, ECL, MOS, and CMOS outputs makes it suitable for use in a wide range of applications.
