Key Features

  • Quad op-amp in a single 14-Pin SOIC package, saving board space
  • Wide supply voltage range: 5V to 28V single supply or ±2.5V to ±14V dual supply
  • 1.2MHz gain-bandwidth product suitable for audio and signal conditioning
  • Low input bias current (150nA typ) for high-impedance sensor interfaces
  • 70dB minimum CMRR for excellent noise rejection in differential measurements

Applications

The LM124D is widely used in industrial sensor signal conditioning, battery-powered portable equipment, and active filter designs. Its quad configuration makes it ideal for multi-channel amplification in process control systems and instrumentation. The wide supply voltage range and low power consumption also suit it for automotive and consumer electronics applications.

Frequently Asked Questions

What is the supply voltage range of the LM124D?

The LM124D operates from a single supply of 5V to 28V or a dual supply of ±2.5V to ±14V, making it versatile for both battery-powered and regulated power supply systems.

What are the key electrical specifications of the LM124D op-amp?

The LM124D features a 1.2MHz gain-bandwidth product, 70dB minimum common-mode rejection ratio (80dB typical), 0.15µA typical input bias current, and 0.1µA maximum input offset current at 25°C.

What package does the LM124D come in and what are its typical applications?

The LM124D is available in a 14-Pin SOIC (Small Outline Integrated Circuit) package. It is commonly used in signal conditioning, active filters, instrumentation amplifiers, process control, and audio amplification circuits.

Is the LM124D suitable as a replacement for the LM324?

Yes, the LM124D is pin-compatible with the LM324 family. Both are quad op-amps with similar electrical characteristics; the LM124 series is rated for a wider temperature range (−55°C to 125°C) compared to the standard LM324.
