L272D013TR

Overview

The L272D013TR is a dual high-gain power operational amplifier manufactured by STMicroelectronics. It features a gain-bandwidth product of 350 kHz and a slew rate of 1 V/us. The device supports supply voltages ranging from 4 V to 28 V (dual) or 2 V to 14 V (single). Key electrical parameters include an input offset voltage of 60 mV, input bias current of 2.5 uA, and a maximum output current of 1 A per channel. It operates within a temperature range of -40 C to +85 C and includes shutdown functionality.

Feature Summary

• High output current capability up to 1 A per channel for driving low-impedance loads
• Integrated thermal shutdown protection for enhanced reliability under overload conditions
• Low saturation voltage design for efficient power delivery in servo and power applications
• Input compatibility with ground potential allowing single-supply operation

Applications

• Servo amplifiers requiring high gain and power output
• Power supply circuits needing robust signal conditioning
• Optical disc drive mechanisms and VCR systems

Procurement Notes

Verify the specific suffix '013TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official datasheets as regulatory requirements vary by region. Ensure the ordering part number matches the exact package type required for your PCB layout. Cross-reference manufacturer documentation for any recent lifecycle changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when application demands exceed standard op-amp output capabilities but do not require discrete power stages. The dual-channel configuration simplifies designs needing two independent high-current outputs. Consider the 350 kHz bandwidth limit for frequency response requirements. Evaluate thermal management needs given the 1 A output capability and integrated shutdown feature.

Part Context

The L272 series represents STMicroelectronics' solution for integrating operational amplifier precision with power stage capability. This family targets applications previously requiring separate amplifier and driver components. The L272D013TR variant specifically denotes the surface-mount SOIC-16 package version supplied in tape-and-reel format for automated assembly processes.
