L2722

L2722 Description

The L2722 from STMicroelectronics is a dual general-purpose operational amplifier designed for high-current output applications. Operating within a 4V to 28V supply range, it delivers 1.5A output current per channel, making it suitable for driving heavy loads. With a 1.2MHz gain bandwidth product and 2V/µs slew rate, it balances speed and stability for medium-frequency analog circuits. The device exhibits low input bias current (200nA) and moderate input offset voltage (10mV), ensuring reasonable precision in signal conditioning. Packaged in an 8-pin Mini DIP (Tube), it is RoHS3 compliant and REACH unaffected, meeting modern environmental standards.

L2722 Features

• High Output Current: 1.5A per channel enables direct drive of motors, solenoids, or other high-current peripherals.
• Wide Supply Range: 4V to 28V operation supports diverse power configurations.
• Balanced Performance: 1.2MHz GBW and 2V/µs slew rate for stable mid-bandwidth amplification.
• Robust Packaging: Through-hole 8-pin Mini DIP for easy prototyping and industrial use.
• Low Power Consumption: 10mA supply current per amplifier optimizes efficiency.
• Compliance: ROHS3, REACH Unaffected, ECCN EAR99 for global deployment.

L2722 Applications

• Motor Drivers: Ideal for DC motor control due to high output current.
• Power Amplifiers: Suitable for audio or servo amplifiers requiring robust drive capability.
• Industrial Automation: Used in solenoid/piezoelectric actuator drivers.
• Test Equipment: Functions in load simulators or current sources for bench testing.
• Legacy Systems: Fits obsolete designs needing through-hole, high-current op-amps.

Conclusion of L2722

The L2722 stands out for its high-current output and versatile supply range, bridging the gap between general-purpose op-amps and power drivers. While obsolete, its through-hole package and robust performance make it valuable for maintenance, industrial systems, and high-load analog circuits. Engineers seeking a cost-effective, high-drive solution for legacy or power-sensitive designs will find it a pragmatic choice.
