L272D

Overview

The L272D is a dual power operational amplifier manufactured by STMicroelectronics. It is designed for applications requiring high gain and significant output power, such as servo amplifiers and power supplies. The device integrates thermal shutdown protection and features low saturation voltage. It supports single or split supply configurations and operates at low voltages with ground-compatible inputs.

Feature Summary

• Integrated thermal shutdown protection
• Low saturation voltage characteristics
• Ground compatible input stage

Applications

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

Procurement Notes

Verify the specific package variant against the datasheet, as the L272 series utilizes Powerdip, Minidip, and SO packages. Confirm that the selected component matches the required pinout and thermal specifications for the intended circuit design before finalizing procurement.

Selection Notes

Select this component when an operational amplifier combined with a power booster is necessary. The L272D provides superior performance in scenarios demanding high output current capabilities alongside standard op-amp functionality within a single monolithic integrated circuit structure.

Part Context

This part belongs to the L272 family of dual power operational amplifiers. These devices are engineered to bridge the gap between signal processing and power delivery, offering a compact solution for driving loads directly without external booster stages in various consumer and industrial electronic equipment.

Replacement Considerations

Consult official substitution lists for equivalent dual power operational amplifiers. Verify compatibility regarding package dimensions, pin configuration, and electrical performance parameters before implementing any alternative components in existing designs.
