Key Features

  • Rail-to-Rail Input/Output (RRIO) for maximum signal swing across full supply range
  • High output current drive with unlimited capacitive load support — no external compensation needed
  • ±15V supply voltage range with 70dB min / 80dB typical common-mode rejection ratio
  • Ultra-low bias current: 0.2µA typical, 1.5µA max at 25°C for precision applications
  • Voltage-feedback architecture with internal frequency compensation for stability

Applications

The LM7321MAX/NOPB is well-suited for precision analog signal conditioning, sensor interface circuits, and active filter designs requiring full rail-to-rail swing. Its high output current and unlimited capacitive load drive make it ideal for driving long cable runs, LCD panels, and buffering ADC inputs in industrial and medical instrumentation. The wide ±15V supply range also supports legacy analog systems and high-dynamic-range audio applications.

Frequently Asked Questions

What supply voltage range does the LM7321MAX/NOPB support?

The LM7321MAX/NOPB operates on a wide supply voltage range of ±15V (dual supply), making it compatible with both modern low-voltage designs and legacy ±12V or ±15V analog systems commonly used in industrial instrumentation.

What does 'unlimited capacitive load' mean for the LM7321?

Unlike many op amps that become unstable when driving large capacitive loads, the LM7321 is specifically designed to drive any capacitive load without external series resistors or compensation networks, simplifying PCB design when buffering ADC inputs or driving cables.

What are the typical applications for the LM7321MAX/NOPB?

This op amp is commonly used in active filters, precision signal conditioning, sensor amplifiers, LCD panel drivers, and medical instrumentation front-ends where rail-to-rail output swing, low bias current (0.2µA typical), and high output current drive are required simultaneously.

What package does the LM7321MAX/NOPB come in?

The LM7321MAX/NOPB is available in a Small Outline (SOIC/SOP) surface-mount package, suitable for automated PCB assembly. The /NOPB suffix indicates it is a lead-free (RoHS-compliant) version, confirmed by the Pbfree Code: Yes specification.
