L2722

Overview

The L2722 is a monolithic dual power operational amplifier manufactured by STMicroelectronics, housed in a Minidip package. It provides an output current up to 1 A with a peak capability of 1.5 A. The device operates on single or split supplies ranging from 4 V to 28 V (±2 V to ±14 V). Key electrical characteristics include a gain-bandwidth product of 1.2 MHz, a slew rate of 2 V/µs, and an input offset voltage of 10 mV. It features thermal shutdown protection at 145°C and includes integrated clamp diodes.

Feature Summary

• Integrated thermal shutdown protection
• Built-in clamp diodes for load protection
• Ground-compatible inputs
• Low saturation voltage

Applications

• Servo amplifiers
• Power supplies
• Compact-disc drives
• Video recorders
• Automotive systems

Procurement Notes

Verify the specific Minidip package configuration when sourcing this component. Confirm that the application environment remains within the specified junction temperature limits to ensure the thermal shutdown mechanism functions correctly. Check datasheet revisions for any updates to absolute maximum ratings before finalizing designs.

Selection Notes

Select the L2722 when high output current is required alongside low-voltage operation. Its ground-compatible inputs simplify interface design with logic circuits. Consider the Minidip package constraints regarding thermal resistance when designing heat dissipation strategies for continuous high-current loads.

Part Context

This component belongs to the L272x series of low drop dual power operational amplifiers. The L2722 specifically utilizes the Minidip package, distinguishing it from the Powerdip (L2720) and SIP-9 (L2724) variants. All members share identical internal circuitry and electrical performance specifications.
