L272D2

Overview

The L272D2 is a dual power operational amplifier manufactured by onsemi, housed in a 16-SOP package. It operates within a supply voltage range of -4V to 28V and supports an operating temperature from -25°C to +85°C. Key electrical parameters include a typical gain-bandwidth product of 350 kHz, a slew rate of 1 V/μs, and a maximum output current of 0.7A per channel. The device features thermal shutdown protection at 160°C and offers high large-signal voltage gain.

Feature Summary

• Provides high output current capability up to 0.7A for driving low impedance loads
• Includes thermal shutdown protection to prevent damage during overheating events
• Features ground-compatible inputs allowing operation with single or split supplies
• Delivers large common-mode and differential-mode input voltage ranges

Applications

• Servo amplifiers
• Power supplies
• Compact disc players
• Video cassette recorders (VCR)
• Monitor circuits

Procurement Notes

Verify the specific manufacturer origin, as the L272 series was originally developed by Fairchild Semiconductor and later acquired by onsemi. Confirm that the 16-SOP package variant matches the required pinout and mechanical dimensions for the target PCB layout. Ensure compliance with RoHS standards if applicable to the manufacturing batch.

Selection Notes

Select this component when a dual-channel power amplifier with moderate bandwidth is required. The L272D2 is suitable for applications needing direct drive capabilities without external booster stages. Consider the 8-DIP version if through-hole mounting is preferred over surface mount technology.

Part Context

This part belongs to the L272/L272A family of dual power operational amplifiers designed for general-purpose power amplification tasks. The 'D2' suffix specifically denotes the 16-SOP surface-mount package configuration, distinguishing it from the 8-DIP leaded package variants available in the same series.

Replacement Considerations

L272M serves as a functional equivalent in an 8-DIP package.
