L272AM

Overview

The L272AM is a dual power operational amplifier manufactured by onsemi, designed for high-output applications. It features two channels within an 8-pin PDIP package suitable for through-hole mounting. Key electrical specifications include a gain-bandwidth product of 350 kHz and a slew rate of 1 V/µs. The device supports single or split supply voltages ranging from 4 V to 28 V total, with individual rails as low as 2 V. It delivers up to 700 mA output current per channel and includes thermal shutdown protection. Operating temperatures range from -25°C to +85°C.

Feature Summary

• Dual-channel power amplification with ground-compatible inputs
• Integrated thermal shutdown protection
• Low saturation voltage capability
• Large common-mode and differential mode input voltage range

Applications

• Servo amplifiers
• Power supplies
• Compact disc players
• VCR systems

Procurement Notes

Verify the specific suffix 'AM' against the official datasheet to confirm pinout and package dimensions, as variations exist within the L272 family. Confirm RoHS compliance status directly with the manufacturer documentation. Check for active production status, as some variants may be discontinued or have limited availability. Ensure the selected package matches the PCB footprint requirements for through-hole installation.

Selection Notes

Select this component when high output current near 1 A is required in a dual-op-amp configuration. It is suitable for designs needing ground-referenced inputs and operation at low supply voltages. Consider the 350 kHz bandwidth for moderate-speed signal processing. Verify that the thermal management strategy accommodates the power dissipation during high-current loads.

Part Context

The L272 series consists of monolithic integrated circuits intended for power operational amplifier roles. Available in Powerdip, Minidip, and SO packages, these devices combine high gain with significant output power capabilities. They are engineered to replace combinations of standard op-amps and external power boosters, simplifying circuit design for audio and industrial applications.
