L272D013TR - 16V 250kHz Dual Power Op Amp | STMicroelectronics
부품 번호: L272D013TR ✓ 활성L272D013TR 개요
An operational amplifier is an amplifier IC that compares an input voltage with a feedback reference and drives its output to reduce the difference between them. The L272 belongs to the power-operational-amplifier category, where high output current and low output impedance distinguish it from general-purpose signal amplifiers. Its dual architecture provides two independent amplifier channels in one package, reducing board area in applications that require parallel gain, current, or drive stages.
The L272D013TR operates from 4 V to 28 V and offers a 250 kHz gain-bandwidth product with a 1 V/µs slew rate. STMicroelectronics describes the device for low-impedance loads and applications including servo amplifiers, power supplies, compact-disc equipment, and video-recorder equipment. These characteristics make it useful when the output must drive a heavier load than a conventional precision op amp can accommodate.
The power-amplifier architecture requires attention to output-device dissipation, supply headroom, and thermal management. Because this dual amplifier can deliver substantial output current, PCB copper area and thermal design influence junction temperature and reliability. Output-current capability, thermal resistance, offset voltage, input-bias current, and detailed absolute-maximum ratings should be confirmed against the manufacturer datasheet before committing a design to production.
Typical implementations include servo-motor drive assistance, regulated power-supply loops, audio output stages, active filters, motor-control interfaces, and general-purpose power buffering. In these systems, the L272 can replace a discrete op-amp and power-transistor combination when its voltage, bandwidth, slew-rate, current, thermal, and stability characteristics satisfy the load requirements.
Design the supply path and output stage for the intended transient load. Keep high-current return currents short, provide local supply bypassing, and verify that the selected package has adequate copper for heat removal. Compensation, gain selection, and load stability depend on the surrounding feedback network and output impedance, so prototype the final topology before production release.
This page combines the L272 family application context, package information, sourcing guidance, drop-in-replacement analysis, and practical thermal and layout considerations. It is designed to help engineers compare the L272D013TR against same-family devices and determine whether its dual-channel power-amplifier architecture fits a specific board-level design.

일반적인 애플리케이션
L272D013TR 적합 용도: 6 애플리케이션s: Servo Amplifier Drive, Regulated Power-Supply Control, Audio Power Output Stage, Motor-Control Interface, Active Filtering and Instrumentation, Video and Compact-Disc Equipment.
Servo Amplifier Drive
The L272D013TR is appropriate for servo-amplifier assistance because the STMicroelectronics L272 family is intended for power operational amplifiers used in servo systems. Its 250 kHz gain-bandwidth product and 1 V/µs slew rate provide useful control-loop bandwidth, while the power-output stage is intended to drive lower-impedance loads than a general-purpose signal op amp. The 4 V to 28 V supply range supports servo systems using a conventional industrial bus. In a practical implementation, the amplifier can sit in the forward drive path, with compensation and feedback selected for the motor, load inertia, and required stability. Because the device can deliver up to 0.7 A per amplifier, the PCB must provide short current paths and sufficient copper for thermal dissipation.

Regulated Power-Supply Control
The L272D013TR can serve as a power-buffer or error-amplifier stage in a regulated power supply because the L272 family is specifically identified for power-supply applications. A 4 V to 28 V operating range permits use from modest industrial rails to higher-voltage systems, while the 250 kHz gain-bandwidth product supports feedback-loop correction and the 1 V/µs slew rate improves large-signal response. Place the amplifier near the power stage or load so that feedback and high-current return paths remain short. The primary engineering tradeoff is dissipation: even though the output stage can source or sink substantial current, thermal design and copper area determine achievable continuous output. Compensation must be evaluated with the selected power topology and output network.
추천
Audio Power Output Stage
The L272D013TR is suited to audio-buffer applications that require more output drive than a conventional small-signal amplifier. The L272 family's low-impedance-load capability supports power-amplifier stages, while its 250 kHz gain-bandwidth product and 1 V/µs slew rate provide response beyond basic audio bandwidth. In a design, the device can follow an upstream voltage-control or error-amplifier stage and drive a speaker, transducer, or line-driving load. The two amplifier circuits in one 16-pin SO package can be used for stereo channels when each channel's drive and thermal requirements are satisfied. Designers should verify output swing, distortion, stability, and thermal rise against the actual load. The TR ordering code indicates a shipping format associated with automated assembly.

Motor-Control Interface
The L272D013TR can provide the output-drive element of a motor-control interface when the controller produces a command signal but cannot directly drive the motor winding. The power-amplifier architecture targets low-impedance loads, and its 1 V/µs slew rate helps translate control commands into a stronger output waveform. The 250 kHz gain-bandwidth product should be checked against the required loop bandwidth, while the 4 V to 28 V supply range offers flexibility for industrial voltage rails. In a practical implementation, the amplifier may drive a current-controlled motor stage rather than the motor directly. Compensation must prevent oscillation with the motor's back-EMI, wiring inductance, and load dynamics. PCB layout should keep output current out of sensitive feedback paths and provide adequate thermal relief.
추천
Active Filtering and Instrumentation
The L272D013TR can be used where a filter or instrumentation buffer must drive a relatively low-impedance sensor, transducer, or measurement load. Although its 250 kHz gain-bandwidth product is lower than that of many precision signal amplifiers, its power-output stage provides the drive needed when the measured signal must also excite downstream equipment. The dual-circuit arrangement allows two buffered channels in one 16-pin SO package, reducing component count where two similar signals are processed. Input offset voltage and bias current are important because they affect low-level measurement accuracy and must be checked against the required common-mode and impedance conditions. Feedback-component tolerances and amplifier stability should be characterized with the complete source and load network rather than with an ideal source.
추천
Video and Compact-Disc Equipment
The L272D013TR is directly relevant to legacy video and compact-disc equipment because STMicroelectronics identifies the L272 family as suitable for compact-disc and video-recorder equipment. The device's power-operational-amplifier architecture can provide low-impedance drive in signal-chain stages that require more current than a conventional small-signal amplifier. Its 250 kHz gain-bandwidth product and 1 V/µs slew rate are suitable for many closed-loop audio and control paths, although the final bandwidth allocation depends on the feedback network and load. A redesigned modern implementation should verify obsolete-component sourcing, signal-integrity margins, and stable operation across temperature. Lead-free and environmental compliance should be confirmed for the exact ordering code before use in a newly manufactured consumer product.

설계 노트
The L272 family can deliver output current up to 0.7 A, making package dissipation and copper area central to the design. Estimated: with a 5 V supply, a 1 V output swing, and continuous 0.5 A load, output-stage dissipation is approximately 2 W before accounting for the rest of the circuit. Check the manufacturer thermal-resistance data, distribute copper around the package, and verify the worst-case ambient temperature and load condition before production.
Separate high-current output paths from feedback and signal-reference traces. Place input and compensation components close to their associated pins, use a low-impedance ground return, and keep the exposed copper path from the package to the load as short as practical. The 1 V/µs slew rate can move output current rapidly, so long loops or shared supply impedances can introduce coupling or instability even when the nominal gain-bandwidth product is acceptable.
Decouple each supply rail locally and provide bulk energy storage appropriate for the load step. Do not treat the 4 V to 28 V operating range as permission to operate without headroom: output swing, output-current capability, and thermal limits vary with supply voltage and load. Confirm the absolute-maximum ratings, quiescent current, output-swing behavior, and power-derating requirements in the manufacturer documentation before selecting the supply rails.
Do not substitute a generic dual op amp solely because it also uses a 16-pin SO package. The L272D013TR is a power operational amplifier, and a small-signal replacement may fail to supply the required 0.7 A-class drive or dissipate the expected load. Verify numbered pins, feedback connections, supply limits, output swing, input offset, bias current, stability, and thermal performance for every proposed replacement.
