L272M

Overview

The L272M is a dual power operational amplifier manufactured by STMicroelectronics. It features a gain-bandwidth product of 350 kHz and a slew rate of 1 V/µs. The input offset voltage is 15 mV with an input bias current of 300 nA. Operating from a supply voltage range of 4 V to 28 V, it delivers up to 700 mA output current per channel. The device includes thermal shutdown protection and operates within a temperature range of -40°C to +85°C.

Feature Summary

• High output current capability for driving loads directly
• Integrated thermal shutdown protection for reliability
• Low saturation voltage for efficient power delivery

Applications

• Servo amplifiers
• Power supplies
• Compact disc players
• Video cassette recorders

Procurement Notes

Verify the specific manufacturer designation as the L272M part number has been produced by multiple vendors including onsemi. Confirm the exact datasheet version and pinout compatibility before integration. Check component status as some listings indicate end-of-life or limited availability. Ensure the package type matches the design requirements.

Selection Notes

Select this component when high output current is required without external booster stages. It serves as a direct replacement for operational amplifier and power booster combinations. Consider the 700 mA limit and thermal management needs. Verify ground-compatible input requirements against the signal source.

Part Context

The L272 belongs to a series of monolithic integrated circuits designed for power amplification. It is available in various packages including Powerdip, Minidip, and SO types. The series is engineered for applications requiring high gain and significant output power capabilities in compact forms.
