L2720D13TR - 1A Dual Power Op Amp | STMicroelectronics

STMicroelectronics L2720D13TR is a dual low-side power operational amplifier capable of delivering output current to 1 A. It operates from single or split supplies, accepts large common-mode and differential-mode input ranges, and is packaged in a 16-lead small-outline SOIC. The device also provides ground-compatible inputs, low input offset voltage, low saturation voltage, clamp diodes, and thermal shutdown. A power operational amplifier is a specialized operational amplifier designed to drive loads such as power transistors, loudspeakers, solenoids, or motor-control stages while delivering substantially more current than a conventional small-signal op amp. Within the broader hierarchy, the L2720 is a dual operational amplifier, a voltage-feedback amplifier, an analog integrated circuit, and a power-management interface component. Key characteristics include two amplifier channels, 1 A output capability, operation with either one supply or split bipolar supplies, and a wide signal range. The manufacturer datasheet identifies low input offset voltage, ground-compatible inputs, clamp diodes, and thermal shutdown as important functional features. Its maximum input offset voltage is listed as 10 mV, input bias current as 1 µA, and common-mode rejection as 84 dB. The L2720D13TR is intended for industrial-grade applications covering an operating temperature range of -40 °C to +85 °C. Its two-channel architecture allows one package to support complementary or paired amplifier functions, while 1 A output capability reduces the need for an external driver when the load and thermal conditions permit direct operation. Ground-compatible inputs are useful in single-supply systems where the signal can approach the lower supply rail. Typical uses include servo-amplifier output stages, power-supply control circuits, compact-disc and VCR motor drives, audio output stages, and industrial actuator drivers. The 16-SOIC package also supports conventional surface-mount assembly, although careful attention to copper area and thermal paths remains necessary when continuous high-current operation dissipates substantial power. For robust layouts, keep the power-loop current path short, provide adequate input and output decoupling, and verify the transistor or load return path independently of sensitive feedback routing. The maximum output current is a capability limit rather than a recommended continuous operating point; calculate junction heating for the actual supply voltage, load current, and ambient environment. This product page combines the manufacturer-level functional description, package and environmental characteristics, application guidance, comparison points, and practical design considerations into a concise engineering reference for amplifier and actuator-drive design.

L2720W13TR

L2720W13TR - Dual 1A Power Op Amp | STMicroelectronics

The STMicroelectronics L2720W13TR is a dual, low-dropout power operational amplifier with two amplifier circuits, 1 A output current capability, and a 16-pin SO16 wide-body surface-mount package. The device is designed for power-control loops that require substantially more output current than a conventional precision op amp can provide. Its monolithic dual-amplifier construction, low-voltage operation, and ground-compatible inputs make it suitable for servo amplifiers, regulated power supplies, audio stages, and industrial control systems. A power operational amplifier is a type of operational amplifier designed to drive heavier loads while maintaining stable operation within its supply rails. The L2720W belongs to the operational-amplifier hierarchy, which includes general-purpose amplifiers, high-current output amplifiers, and power-management signal-conditioning ICs. Unlike a discrete design combining a small-signal op amp with external transistor drivers, the L2720W integrates the drive capability into one IC and can reduce external component count in power-conversion feedback loops. Key characteristics include two independent amplifier channels, 1 A output-current capability, a 2 V/µs slew rate, single- or split-supply operation, a large common-mode input range, low input-offset voltage, and ground-compatible inputs. The low-dropout architecture supports power-supply designs where the regulator output must approach the input rail. Split-supply operation allows the same device to control a midpoint biased around ground, while a single positive supply can support ground-referenced signal systems. The wide-body SO16 package provides separate output-current and thermal considerations that differ from a standard SOIC. Because the amplifier can source or sink high current, PCB copper area, output-current limits, supply bypassing, and heat dissipation are central to reliable operation. The manufacturer's electrical characteristics are specified over a -40 °C to 125 °C ambient-temperature range under defined supply conditions. Typical applications include servo amplifiers, regulated linear power supplies, motor and actuator control, audio power stages, sensor-conditioning paths, and industrial process-control systems. In a servo loop, the L2720W can amplify an error signal and drive a load directly when the load remains within its thermal and electrical limits. In a power-supply feedback path, its 1 A output capability reduces the need for an external booster stage. Designers should check the output-current and thermal limits at the intended voltage, provide low-impedance bypassing at the supply pins, and use adequate PCB copper for heat spreading. The output-current capability does not eliminate the need to limit current during overload or startup. Verify absolute maximum ratings, output-swing behavior, stability requirements, and thermal conditions against the manufacturer datasheet before committing the SO16 footprint to a board. This page consolidates the device identity, operating characteristics, package information, sourcing guidance, and practical design considerations into one engineering-oriented reference. It also identifies possible same-footprint alternatives while distinguishing confirmed facts from parameters that require comparison against the manufacturer documentation.

L2726013TR

L2726013TR - 28V 1.2MHz Dual Op Amp | STMicroelectronics

The STMicroelectronics L2726013TR is a dual low-dropout power operational amplifier with two independent amplifier circuits, 1.2 MHz gain-bandwidth product, and a 28 V maximum supply rating. The device is packaged in a 20-pin small-outline SOIC for surface-mount instrumentation, buffering, and general-purpose signal-conditioning systems. Each amplifier can deliver up to 1 A of output current, enabling the IC to drive higher-capacitance loads than a conventional low-power operational amplifier. A power operational amplifier is a general-purpose amplifier designed to operate from single or split supplies while providing relatively high output-current capability. It belongs to the operational-amplifier hierarchy, where an operational amplifier functions as a voltage-controlled voltage source with very high open-loop gain, high input impedance, and low output impedance. The L27260 series adds low-dropout operation, broad common-mode and differential-mode input ranges, and output-current capability suited to instrumentation and buffering applications. The L2726013TR supports single or split supply operation, with a minimum supply magnitude of 2 V. Typical split-supply configurations include ±3 V, ±5 V, ±9 V, and ±12 V, while its 28 V rating supports higher total-voltage applications. Its 1.2 MHz bandwidth supports general-purpose amplification at moderate frequencies. Thermal shutdown and internal clamp diodes provide additional protection against excessive junction temperature and output overdrive conditions. Two amplifiers in one package make the L2726013TR useful for dual-channel signal paths. A typical instrumentation channel can use one amplifier for input conditioning and the other for active filtering or output buffering. The device can also implement differential-to-single-ended conversion, comparator-style thresholding with appropriate feedback, gain stages, and bridge-sensor excitation interfaces. Ground-compatible inputs allow operation from circuits referenced close to the lower supply rail. Typical applications include low-frequency instrumentation, audio and communication buffers, power-converter control loops, sensor interfaces, active filters, and industrial measurement systems. The 1 A output-current capability is particularly useful where the source must charge or discharge larger output capacitances, although stability should be verified for capacitive loads. The SO-20 footprint also allows both amplifier circuits to be placed in one compact surface-mount package. Design attention should focus on supply headroom, output-current limits, thermal dissipation, and feedback-loop stability. Use the manufacturer datasheet's pinout and recommended application circuit when assigning inputs, outputs, supplies, and compensation connections. Avoid driving highly capacitive loads without checking the recommended compensation network, and calculate worst-case dissipation across the full operating temperature range. This page organizes the L2726013TR's core electrical characteristics, practical application fit, package information, verified source links, and constrained drop-in alternatives. It also highlights where engineers should compare the datasheet limits directly against application requirements before substituting a different amplifier or reusing an existing SO-20 layout.

L272AD2

L272AD2 - Dual 0.7A Power Op Amp, 16-SOIC | onsemi

The onsemi L272AD2 is a dual high-power operational amplifier in a 16-pin SOIC package, designed for low-impedance loads and capable of delivering output current up to 0.7 A. Each device contains two general-purpose amplifier channels and is supported by dual supply operation at up to ±14 V, equivalent to a total supply span of 28 V. A power operational amplifier is an operational amplifier integrated with output-driver circuitry capable of supplying substantially more current than a conventional signal-level op amp. The L272AD2 belongs to the amplifier IC hierarchy that includes general-purpose operational amplifiers, power amplifiers, buffer amplifiers, and analog signal-conditioning ICs. This expanded drive capability makes it useful where a precision error amplifier must directly drive a load rather than only a high-impedance feedback network. Key features of the L272AD2 include two amplifier circuits, output-current capability up to 0.7 A, low-impedance load support, and operation from a ±14 V or 28 V total supply. The L272A version provides tighter specifications than the original L272 according to the manufacturer description. These features distinguish the device from general-purpose packages such as LM324D and NE5534DR, which are optimized for lower current, different noise characteristics, or different drive requirements. The device uses a high-current output stage to bridge the gap between a low-current voltage-feedback control loop and a power load. This arrangement is useful in closed-loop systems where the amplifier must respond to an error signal while directly supplying current to the controlled element. Because this L272AD2 is the A-grade derivative, design engineers should distinguish it from the original L272 when tighter electrical limits are required, but should still verify the complete ordering code and electrical limits against the applicable Fairchild Semiconductor datasheet. Typical uses include servo-amplifier output stages, power-supply control loops, audio power stages, compact-disc and VCR analog signal paths, motor or actuator drivers, and general low-impedance load control. The split-supply capability is useful in bipolar output systems, while the ground-compatible input arrangement supports systems in which the input signal references the midpoint between positive and negative rails. Designs must account for the relatively high power dissipated by the output stage when driving low-impedance loads. Output current should not be treated as a constant-current capability independent of supply voltage, load resistance, and thermal conditions. The 16-SOIC package also requires a sound copper and thermal strategy because sustained output operation can heat the package even when the amplifier is mounted on a conventional PCB. This product page consolidates the verified L272AD2 identity, package, supply, channel-count, and output-current information with application guidance, comparison parameters, and design cautions. It also identifies where detailed limits, pin functions, pricing, and lifecycle details remain unavailable in the supplied source data instead of presenting unverified figures as engineering specifications.

L272AD2TF - 0.7A Dual Power Operational Amplifier | Fairchild Semiconductor

The Fairchild Semiconductor L272AD2TF is a dual high-power operational amplifier designed for low-impedance loads, with output current delivery up to 0.7 A. It is packaged in a 16-pin SOIC and combines two amplifier channels in one package. The device is identified by the L272A family designation, which provides tighter input bias current, input offset voltage, and input offset current specifications than the original L272 family. The L272AD2TF is intended for applications requiring substantial output drive rather than the small signal currents typical of conventional precision amplifiers. A power operational amplifier is an operational-amplifier category optimized for driving low-impedance loads while maintaining useful output voltage and current capability. The L272A belongs to the broader operational amplifier hierarchy, which includes instrumentation, voltage-feedback, current-feedback, audio, and power-buffer devices. Its two-channel construction can reduce component count in stereo audio, motor-control, actuator, power-converter feedback, and general industrial signal-conditioning circuits. The key electrical characteristics visible for this exact part include a 1 V/us slew rate, approximately 350 kHz bandwidth, approximately 1 uA input bias current, and approximately 30 mV input offset voltage. The manufacturer listing identifies the L272A as a dual amplifier with 0.7 A output current capability. These specifications make the part suitable for designs where the load presents a significantly lower impedance than the load handled by a conventional small-signal operational amplifier. Typical applications include audio output stages, motor and solenoid drivers, low-impedance sensor interfaces, power-supply control loops, industrial controls, and communication equipment. In each case, the design must verify the output-current limit, supply-voltage range, output-voltage swing, thermal dissipation, and stability with the actual load. The SOIC-16 package also requires attention to copper area and thermal management when the amplifier operates near its maximum current capability. For robust implementation, start with the manufacturer’s recommended dual-supply or single-supply configuration and use the power and decoupling connections shown in the datasheet. Keep high-current output returns short and connect input and feedback traces away from output-current paths. Confirm the load’s resistance, capacitance, and grounding arrangement before layout because a power amplifier can become unstable when driving nonlinear or highly capacitive loads. This product page combines the exact part identification, verified electrical highlights, package information, sourcing context, and application-focused design guidance for engineers evaluating the L272AD2TF. The manufacturer’s technical documentation remains the controlling reference for absolute maximum ratings, full electrical tables, pin functions, and test conditions.

L272AM - 0.7A Dual Power Op Amp in 8-DIP | onsemi

The onsemi L272AM is a dual high-power operational amplifier in an 8-DIP package, with each amplifier capable of delivering output current up to 0.7 A. The device is designed for low-impedance loads and provides two amplifier channels in one package, making it useful where a conventional small-signal op amp cannot supply the required output current. The L272A version offers tighter specifications for input bias current, input offset voltage, and input offset current than the original L272 family. An operational amplifier, or op amp, is a voltage-feedback analog amplifier that uses differential input voltage to control an output. A power operational amplifier extends this familiar function into higher-current applications. In the product hierarchy, L272AM belongs to the operational-amplifier family, amplifier IC category, and broader analog and mixed-signal semiconductor market. Unlike a general-purpose precision op amp, its defining capability is output-current capability of up to 0.7 A for low-impedance loads. The L272AM combines a dual-amplifier configuration with high output-current capability in a through-hole 8-DIP package. Two independent amplifiers in one package can reduce component count in designs requiring paired signal paths. The specified 0.7 A output-current capability is the principal feature for motor-driver, audio-output, and other power-buffer applications. The L272A tightening in input bias current, input offset voltage, and input offset current supports applications requiring more accurate input-stage behavior than the original L272. The L272AM is intended for low-impedance drive scenarios, where the load draws substantial current or presents a low resistance to ground. Its output stage, rather than merely its small-signal voltage gain, is the central engineering consideration. Designers must account for output-current dissipation, load-return paths, thermal rise, and stability under capacitive or inductive loading. Because the available source material does not provide complete electrical tables, supply limits, gain-bandwidth data, slew rate, or output-saturation values, those parameters should be confirmed in the manufacturer datasheet before release. Typical uses include low-impedance audio amplification, motor and actuator drive interfaces, power-buffer stages, and industrial control or instrumentation circuits that require more output current than a conventional dual op amp can provide. Using both channels can also simplify symmetrical signal conditioning or complementary drive designs. The through-hole DIP package is particularly suitable for leaded assemblies, prototypes, repair products, and industrial equipment where insertion and inspection are more important than board area. For reliable implementation, calculate worst-case output-stage dissipation from the selected supply voltage, output swing, load current, and ambient temperature. Keep output-return current paths short and use a ground plane that can carry the load current without introducing voltage drops. Decouple the supply pins near the device and verify stability with the actual load network. Remote feedback or ground connections should be treated as critical layout elements because high-current outputs combined with imperfect return paths can create feedback errors, oscillation, or unexpected supply transients. This page consolidates the verified onsemi and distributor descriptions, current sourcing links, package information, and practical engineering guidance for the L272AM. It also distinguishes documented facts from missing datasheet parameters and avoids presenting unverified replacement parts as drop-in choices. Engineers can use the comparison and design notes to assess whether the dual high-current output capability suits their load before finalizing the schematic, thermal design, and component sourcing plan.

A power operational amplifier adds a high-current output stage capable of driving lower-impedance loads than a conventional small-signal op amp. In the product hierarchy, the L272D is therefore a dual power operational amplifier, a specialized member of the broader operational amplifier, analog amplifier IC and semiconductor categories. The L272D provides two amplifier circuits in one 16-SO package, reducing board area compared with separate monolithic dual or single-channel power amplifiers. Its 350 kHz bandwidth is useful in servo and power-control loops, while its output-current capability of up to 0.7 A permits driving loads that would overload a standard precision op amp. The available operating-temperature information for L272D specifies -40°C to +85°C, supporting industrial-temperature equipment where that range is suitable. The high gain and high output-power capability make the L272 family applicable where an operational amplifier and external power booster would otherwise be required. The device can serve as the active stage in servo systems, power-supply control circuits and other applications that require substantial output current into low-impedance loads. Because it is a power-output device, thermal design, output-stage stability, load transients and supply decoupling remain central engineering considerations. Typical designs place the L272D close to the load being driven, use local supply bypassing at the amplifier pins, provide stable negative feedback, and verify output-current and thermal limits across worst-case supply and temperature conditions. The available verified data does not include complete output-voltage swing, supply-current, slew-rate, input-offset, gain-bandwidth or thermal-resistance tables, so those values require confirmation in the manufacturer datasheet before final design release. This page combines the verified STMicroelectronics product description, distributor packaging information, operating-temperature and bandwidth data, practical application guidance, and the available cross-reference information.

Its 4 V to 28 V supply range, 250 kHz gain-bandwidth product, and 1 V/µs slew rate make it suitable for power buffers, servo amplifiers, power-supply control, audio amplification, and instrumentation. The L272 family provides the output-current capability normally associated with discrete power stages while retaining the convenience and control of a monolithic amplifier. 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.

L272M - 0.7A Dual Power Operational Amplifier | STMicroelectronics

STMicroelectronics L272M is a high-power dual operational amplifier designed for low-impedance loads and power-buffer applications, with an output current capability of up to 0.7 A per amplifier. The device is supplied in an 8-pin Mini-DIP package and contains two independent amplifier sections. It is intended for applications where conventional operational amplifiers cannot provide sufficient output drive, including servo amplifiers, power supplies, audio equipment, compact disc systems, and video applications. The L272M belongs to the operational-amplifier and power-management IC hierarchy. An operational amplifier is a voltage-controlled amplifier with very high open-loop gain, while a power operational amplifier adds a high-current output stage to drive low-impedance loads. In this device, the internal power-output stage is the defining feature: the amplifier can source or sink substantially more current than a standard signal-level op amp, making it useful as a driver or buffer between a control voltage and a power load. The verified product information identifies the L272M as a dual general-purpose amplifier in an 8-Mini-DIP package. The L272 family is also described as having high gain and high output-power capability, with the L272A offering tighter input bias current, input offset voltage, and input offset current specifications than the standard L272. The L272M is therefore a functional choice when the design requires a dual amplifier with high load-current capability rather than low-noise signal amplification. Key engineering characteristics include a maximum output current of 0.7 A, a supply operating range stated in verified listings as 4 V to 28 V, and an approximately 350 kHz gain-bandwidth indication in one distributor datasheet summary. The L272M is suited to servo and power-supply control loops, audio power stages, compact-disc mechanisms, and legacy video equipment. Its output stage introduces substantial dissipation potential, so load current, supply voltage, ambient temperature, copper area, and thermal-path design must be evaluated together. Typical implementation places the L272M in a feedback configuration so the control node drives the output stage into a defined voltage or current. The feedback network must be stable with the intended load, and the output current capability should not be confused with continuous power dissipation. In servo systems, the amplifier can increase current delivered to a motor-control stage; in power supplies, it can drive a low-impedance feedback node or external power transistor. Audio applications benefit from the higher current drive, although the device is not positioned as a modern low-noise headphone amplifier. The primary design consideration is thermal management. A power amplifier operating near 0.7 A can dissipate several watts depending on supply voltage, output voltage, and load impedance. PCB copper area, proximity to a thermal path, ambient temperature, and the selected package variant determine safe operating conditions. Designers should also verify the exact L272M pinout, output-current limits, supply limits, input common-mode range, and stability limits against the current STMicroelectronics datasheet before production release. This product page combines the verified distributor and manufacturer descriptions with application guidance, packaging information, and a cross-reference comparison. It distinguishes the L272M from lower-current operational amplifiers such as LM324 and from tighter-offset L272A variants, while avoiding unsupported pricing, electrical-limit, and lifecycle assumptions that are not present in the supplied source data.

In the electronics hierarchy, the L272M-ON belongs to the operational-amplifier family, within amplifier ICs and analog signal-processing semiconductors. Its principal role is to amplify a control voltage while driving a low-impedance load that would overload a standard precision amplifier. The primary verified specifications are its dual-circuit architecture, 8-Mini-DIP construction, high-gain/high-output design, suitability for low-impedance loads, and output current up to 0.7 A. According to the onsemi product page, the L272 family was created for applications where an operational amplifier and separate power-booster stage would otherwise be required. Combining those functions can simplify analog power-control circuits while preserving a conventional op-amp signal interface. The L272M-ON is relevant to power supplies, servo amplifiers, audio equipment, compact-disc mechanisms, and other applications requiring high output current from an operational-amplifier stage. Its two independent channels can also implement dual feedback loops, push-pull driver stages, motor-control loops, or two coordinated actuator-control channels. Exact supply voltage, gain-bandwidth, slew rate, thermal resistance, and common-mode limits must be confirmed in the manufacturer datasheet before final circuit design. Thermal design is a central implementation consideration. A device capable of delivering up to 0.7 A can dissipate substantial power when the output voltage and load current are both appreciable. Designers should calculate worst-case dissipation, provide adequate copper around the Mini DIP leads, and account for the package pin limits in the selected operating mode. Negative or bidirectional drive requirements also need careful output-stage and grounding analysis. This page combines manufacturer-family information, verified distributor availability, package details, practical application guidance, and a structured comparison of same-footprint alternatives. It also identifies missing electrical details instead of estimating them, helping engineers distinguish confirmed L272M-ON characteristics from values that still require review of the original manufacturer datasheet.

L6360TR - 32.5V IO-Link Master Transceiver | STMicroelectronics

STMicroelectronics L6360TR is an IO-Link communication master transceiver IC for industrial sensor and actuator interfaces, operating from 18 V to 32.5 V and supporting PHY2 three-wire communication in COM1, COM2, and COM3 modes. The device provides a protected 500 mA L+ high-side driver, programmable high-side, low-side, or push-pull output stages with less than 2 Ω output resistance, and an additional IEC 61131-2 type 1 input. An IO-Link master transceiver is a specialized interface integrated circuit that combines digital communication, sensor excitation, and discrete input detection for industrial automation. Within the hierarchy of interface ICs, transceivers, and industrial communication semiconductors, the L6360 provides the electrical interface between a controller and an IO-Link sensor or actuator. It is designed to simplify master ports operating at COM1, COM2, or COM3 communication speeds. The L6360 supports COM1 at 4.8 kbaud, COM2 at 38.4 kbaud, and COM3 at 230.4 kbaud. Its protected 500 mA L+ high-side driver supplies connected sensors, while the programmable output stage can operate as high-side, low-side, or push-pull with less than 2 Ω resistance. These functions support flexible connection of compatible industrial sensors, actuators, and digital input devices. The monolithic transceiver architecture integrates an IO-Link physical layer with sensor power and input circuitry. Its 18 V to 32.5 V supply range accommodates common industrial control environments, and its VFQFN-26 exposed-pad package supports compact surface-mount layouts. The exposed thermal pad must be connected to ground and used for heat spreading when operating at elevated ambient temperatures or driving higher output loads. Typical uses include IO-Link master ports in factory automation, proximity and photoelectric sensors, industrial actuators, and distributed control systems. The L6360 is also appropriate when a machine controller must support multiple IO-Link communication speeds while combining a protected sensor supply with an additional digital input. PCB design should follow the manufacturer datasheet for pin assignment, exposed-pad connection, and external component selection. Decoupling must be placed close to the supply pins, the exposed pad should have adequate thermal-via and copper support, and high-current output paths should be sized to limit voltage drop across the L+ driver. This page combines verified manufacturer specifications, distributor pricing, package details, application guidance, and drop-in replacement research. The replacement analysis specifically distinguishes confirmed equivalents from related interface products that cannot be treated as pin-compatible substitutes.

The STMicroelectronics L6362A is an IO-Link and SIO mode transceiver device compliant with the PHY2 (3-wire connection) specification, supporting COM1 (4.8 kbaud), COM2 (38.4 kbaud), and COM3 (230.4 kbaud) communication modes. It is housed in a 12-pin VFDFPN (3x3 mm) package with an exposed pad, designed for the industrial 24 V environment. An IO-Link transceiver is a specialized interface IC that sits between an industrial microcontroller and a 3-wire sensor or actuator cable, implementing the physical layer of the IO-Link single-drop digital communication protocol standardized under IEC 61131-9. The IO-Link protocol itself operates within the broader industrial sensor and actuator hierarchy (sensor front-end -> IO-Link PHY -> industrial fieldbus / PLC), and the L6362 belongs to the class of dedicated PHY2 transceivers that combine physical line driving, power supply conditioning, and protection in a single monolithic device. Key features include a 10 mA selectable linear regulator, 5 V and 3.3 V compatible I/Os, a 0.3 A output current intervention threshold, and a fully protected output stage that can be configured as high-side, low-side, or push-pull. The output driver can sink and source resistive, capacitive, and inductive loads typical of industrial sensor coils, and the device integrates reverse-polarity, overcurrent, and thermal protection.

The exposed pad on the VFDFPN-12 package keeps junction temperature within safe limits during sustained output currents near the 0.3 A intervention threshold. Typical applications include industrial sensors, factory automation nodes, process-control transducers, and any IO-Link-compatible smart sensor or actuator port. The wide supply voltage tolerance and integrated protection make it well suited to harsh 24 V industrial environments with long cable runs.

L6364Q - Dual-Channel IO-Link Transceiver | STMicroelectronics

The STMicroelectronics L6364Q is a dual-channel IO-Link and SIO transceiver IC in a 20-pin QFN (4x4 mm) package, designed as the PHY interface between a microcontroller and the 24 V industrial sensor/actuator signaling cable. It embeds two physical channels with selectable 3.3 V / 5.0 V / high-side driver modes and integrates 50 mA 3.3 V and 5.0 V LDO regulators plus a DC-DC converter to supply the host MCU and external circuitry from the 24 V rail. As an IO-Link PHY, the L6364Q is a bridge transceiver (interface IC) positioned in the industrial-sensor signal chain: MCU -> IO-Link transceiver -> 24 V cable -> IO-Link master. It supports M-sequence handling, wake-up pulse generation, and SPI configuration from the host microcontroller so the device can be reused across discrete sensors, actuators, and binary (SIO) legacy modes. Key features include a wide 8 V to 36 V operating supply range compatible with industrial 24 V rails, integrated reverse-polarity and over-current protection on the high-side drivers, two independent CQ channels, dual LDO regulators (3.3 V and 5.0 V at 50 mA each) for host MCU supply, integrated DC-DC converter, and -40 C to +150 C extended industrial temperature range. The 20-pin QFN (4x4 mm) package minimizes PCB area for space-constrained sensor heads. Internally the L6364Q combines two C/Q output drivers with current limiting, two LDO regulators with power-good indication, a DC-DC controller for energy-efficient 24 V-to-low-voltage conversion, and an SPI interface for M-sequence parameterization. Compared with discrete IO-Link implementations, the L6364Q shrinks the BOM by replacing multiple protection devices, regulators, and the DC-DC passives with one qualified IC. Typical applications include industrial binary sensors and proximity switches, factory automation actuators with IO-Link connectivity, IO-Link sensor hubs and junction boxes, smart valve and valve-position feedback modules, robotics I/O modules, and process-control instrumentation. The wide input voltage range and integrated protection suit 24 V factory bus operation, while the dual channels enable single-chip two-port sensor nodes. When designing with this part, ensure that thermal management of the QFN exposed pad is adequate - the dual LDO currents plus DC-DC losses can produce 500 mW dissipation at full load. Use the SPI interface to switch from SIO mode to IO-Link mode dynamically without disturbing the in-progress IO-Link communication frame.

L6451013TR - 28-Channel Inkjet Driver, 5.25 V | STMicroelectronics

The STMicroelectronics L6451013TR is a 28-channel inkjet print-head driver integrated circuit supplied in a 44-lead PLCC package. It operates from a nominal 5.25 V maximum supply rating, with distributor technical data also identifying a 4.75 V to 5.25 V supply range and a 0°C to 70°C commercial temperature grade. The device is designed for driving the high-voltage, high-current print-head loads found in inkjet printing equipment. An inkjet driver is a specialized interface IC that converts low-voltage logic commands into controlled high-voltage and high-current drive signals for piezoelectric inkjet nozzles. In the system hierarchy, this device is a printer-specific peripheral driver within the broader interface IC and power-driver categories. Its 28 output channels allow one controller to manage multiple print-head elements while reducing the number of discrete drivers required at the board level. The L6451013TR is listed as a 28-channel driver with a nominal peak output current limit of 2 A and a maximum supply voltage rating of 5.25 V. The 44-terminal PLCC package provides the mechanical footprint used in the original inkjet-printer controller boards. The commercial temperature range supports operation in controlled indoor printer and imaging environments, but the 0°C to 70°C limit is a key constraint for designs operating across wider industrial temperature ranges. Typical applications include inkjet print-head carriage electronics, multi-nozzle print-head assemblies, printer engine control boards, and specialized inkjet dispensing systems. Because it is a dedicated 28-channel print-head driver rather than a general-purpose logic buffer, its timing inputs, protection features, and pin functions are intended for a particular inkjet drive architecture. The principal design consideration is the relationship between the 2 A nominal peak output current rating, the inductive or capacitive load presented by the print head, and the protection network connected to each channel. PCB routing must minimize loop area in high-current drive paths, and unused or reserved outputs should be handled according to the manufacturer pin-description table. Production quantities should be confirmed before layout release because this is an older specialized printer-driver family with limited channel-count substitution. This page consolidates package, channel-count, supply, temperature, and output-current information into a structured engineering reference. It also distinguishes the documented L6451013TR ratings from specifications that must be taken directly from the manufacturer datasheet, including precise channel timing, dropout behavior, and protection thresholds.

L6783ATR - Power Supply Op Amp | STMicroelectronics

The STMicroelectronics L6783ATR is a power-supply operational amplifier in the L6783 series, supplied in an 8-pin SOIC surface-mount package. It is intended for linear signal-conditioning and power-control circuits, with the exact input-voltage range, output-current capability, gain-bandwidth product, slew rate, and thermal limits specified by the manufacturer datasheet. The part is listed as active in the verified product references. An operational amplifier, commonly called an op amp, is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. The operational-amplifier category belongs to the broader linear-IC and amplifier-IC hierarchy, where precision gain, low distortion, stability, and output-drive capability determine suitability. A power-supply-oriented op amp is commonly selected when the signal or feedback node must operate from a supply rail higher than that of a conventional low-voltage amplifier. The L6783ATR's principal verified identifiers are its manufacturer, MPN, power-supply amplifier classification, active lifecycle status, and 8-pin SOIC package. Its “ATR” ordering suffix is associated with tape-and-reel production packaging, making it suitable for automated surface-mount assembly. Numerical electrical ratings are not reproduced on the supplied distributor search pages, so they are deliberately marked as data needed rather than inferred from unrelated amplifier families. A proper design review should begin with the STMicroelectronics L6783 datasheet, including its input common-mode range, output swing, supply-voltage limits, unity-gain stability, noise, offset voltage, slew rate, and recommended application circuit. These parameters determine whether the amplifier can directly drive the intended load or whether a buffer stage is required. The exposed thermal behavior of the SOIC package must also be checked against the dissipation expected at the selected supply voltage and output current. Typical design contexts include power-supply feedback and error-amplifier positions, current-control loops, analog signal conditioning, and instrumentation interfaces. In each case, the L6783ATR must operate inside its verified voltage and common-mode limits, maintain loop stability, and preserve signal integrity at the required bandwidth. Because those limits are absent from the supplied data, final suitability must be confirmed against the manufacturer documentation. For PCB implementation, place the device close to its feedback and compensation components, provide a low-impedance ground return, and decouple each supply pin with the capacitance and layout explicitly recommended by the manufacturer. Avoid adding external compensation unless the application circuit and stability analysis support it, since unnecessary components can alter bandwidth and transient response. This page consolidates the verified manufacturer identity, active status, distributor references, package information, ordering suffix, and source links while clearly separating unknown electrical data. It also provides replacement-search guidance and engineering checks without fabricating amplifier ratings or unsupported drop-in cross-references.

L9613B - ISO 9141 Medium-Speed Data Interface | STMicroelectronics

The STMicroelectronics L9613B is a monolithic medium-speed data-interface IC containing standard ISO 9141-compatible interface functions. The manufacturer identifies the L9613 as a monolithic integrated circuit intended for automotive data-interface applications, while the L9613B ordering code is the subject of the supplied distributor and datasheet records. Its core function is to provide the physical-layer interface required by ISO 9141-compatible diagnostic communication systems. The supplied L9613 datasheet is 15 pages according to the verified document listing. An ISO 9141-compatible data interface is a wired automotive communication interface that connects an automotive diagnostic or test system to a vehicle network through defined K-line and related signal functions. Within the product hierarchy, the L9613B is a monolithic interface IC, a communication transceiver, and therefore a semiconductor-level realization of ISO 9141 physical-layer functions. This classification distinguishes it from general-purpose logic ICs, memory devices, microcontrollers, and analog power-management components. The verified manufacturer material confirms several important implementation details. The device includes standard ISO 9141-compatible interface functions. According to the manufacturer datasheet, the K, LO, and RX outputs have output-voltage behavior that varies with output current, including a transition related to RON multiplied by IOUT and a 2 × RON × IOUT plus UBE condition. The document also states that K, RX, and LI pins include protection against overvoltage, short circuits to ground or VS, and being driven beyond the supply rails. TX, RX, and LI receive comparable protection when internal pull-up behavior is considered. L9613B is intended for medium-speed data-interface systems using ISO 9141-compatible signaling. Its monolithic construction consolidates the required interface functions into one package, helping designers reduce the number of discrete interface elements around a vehicle diagnostic connector or tester. The documented output behavior makes the K, LO, and RX nodes important when designing cable termination, fault-recovery behavior, and logic-level compatibility. Exact electrical limits, timing values, supply range, and package dimensions must be taken from the manufacturer datasheet for production design. Typical use cases include automotive diagnostic testers, engine-control-unit service interfaces, vehicle workshop equipment, and ISO 9141-compatible electronic control modules. In these systems, the L9613B provides the physical-layer interface between a controller and an external diagnostic tool. Selection should account for the target vehicle network, cable length, bus topology, connector standard, protection requirements, and whether the interface must support legacy ISO 9141 rather than a newer protocol. The L9613B is not a general-purpose CAN transceiver and should not be treated as a substitute for CAN, LIN, or OBD-II protocol engines. For implementation, follow the manufacturer’s recommended input, output, decoupling, grounding, and protection arrangements. Verify every external resistor, capacitor, connector, and transient-protection device against the absolute maximum ratings and application diagrams in the L9613 datasheet. PCB signal integrity and automotive transient immunity are especially important because the interface connects directly to conductors entering a vehicle environment. Do not infer package pin numbers or package compatibility from distributor descriptions alone; use the official pin configuration before layout or substitution. This page consolidates the verified STMicroelectronics product page, manufacturer PDF, distributor listings, and targeted cross-reference results. It also separates confirmed ISO 9141 functionality from unverified quantities, making the documentation useful for preliminary design evaluation, sourcing, datasheet discovery, and drop-in-replacement investigation without presenting missing electrical or packaging data as established facts.

STMicroelectronics L9613B013TR is a monolithic ISO 9141-compatible automotive interface transceiver with one transmitter and one receiver, supplied in an 8-pin SOIC package. Its operating supply range is 4.8 V to 36 V, with transient operation up to 40 V. The interface is designed for K-line communication links in vehicle electronic control units and body electronics modules. An ISO 9141 interface transceiver is an integrated circuit that combines a line driver and line receiver with the electrical interface required by a K-line serial network. It belongs to the automotive interface IC category, where a controller uses a physical-layer transceiver to exchange diagnostic or application data with a vehicle bus. The L9613 provides the hardware layer between a microcontroller's serial I/O signals and the vehicle wiring harness. The L9613B013TR operates from a 4.8 V minimum supply and reaches a 36 V maximum supply, while tolerating transients to 40 V. Reverse-battery protection extends to VS values down to -24 V. These characteristics make the device suitable for automotive electrical environments where supply transients, load dumps, and incorrect battery polarity must be considered. A maximum signaling rate of 130 kbps is identified for the component. STMicroelectronics describes the L9613 as a monolithic integrated circuit containing standard ISO 9141-compatible interface functions. Integrating the transmitter and receiver reduces the number of external line-interface components required around a vehicle diagnostic controller. The 8-pin SOIC outline is compact enough for body-control and engine-control electronics while remaining compatible with standard small-outline surface-mount assembly methods. Typical applications include automotive diagnostic interfaces, engine control units, transmission controllers, body control modules, instrument clusters, immobilizers, and other embedded vehicle systems that communicate over a K-line physical layer. Using a dedicated transceiver helps isolate the controller from the wired diagnostic network and supports operation across the voltage range expected in automotive electrical systems. PCB implementation should follow the manufacturer's application diagram for decoupling, connector-side protection, and signal routing. Keep the transceiver close to the vehicle connector or bus interface, provide a stable local supply reference, and verify the connected ECU’s logic levels. The SOIC footprint leaves adequate routing space for bypassing and external protection components, but automotive transient and ground-loop requirements remain the dominant layout constraints. This product page combines the manufacturer interface description with package, voltage, speed, and sourcing details, then adds pin-assignment guidance, practical PCB considerations, application-specific selection advice, and a comparison of documented alternative variants. Engineers can use these notes to evaluate the L9613B013TR for an existing ISO 9141 circuit before requesting a quote and confirming supply availability.

L9615D - 500 kbaud CAN Transceiver | STMicroelectronics

The STMicroelectronics L9615D is a bidirectional 1/1 CAN bus transceiver with signal-conditioning capability for CAN controllers, data rates up to 500 kbaud, and an 8-pin SOIC package. It supports both shielded and nonshielded CAN bus lines, generates differential transmitter outputs, and includes selectable slope control for 500 kbaud and 125 kbaud operation. Its CAN outputs are short-circuit protected to 36 V, while shutdown detection helps isolate faulted bus conditions. A CAN transceiver is an interface IC within the broader transceiver and physical-layer hierarchy. It converts logic-level TXD and RXD signals from a CAN controller into a differential CANH/CANL bus output and converts the received differential bus state back into a controller-compatible RXD signal. The L9615 therefore belongs to the CAN interface and industrial communication networking category, where robust physical-layer behavior helps a controller communicate reliably over long, noisy wiring harnesses. The L9615D supports data rates up to 500 kbaud and meets ISO/DIS 11898 requirements stated in the manufacturer-related datasheet information. Two adjustable slope-control states accommodate 500 kbaud and 125 kbaud networks, allowing engineers to reduce radio-frequency interference and electromagnetic interference through controlled edge rates. Differential signaling provides common-mode rejection, bidirectional operation supports both transmit and receive paths, and 36 V short-circuit protection improves robustness against accidental bus faults. The L9615 uses slope control as an important signal-integrity feature rather than relying only on rise and fall-time behavior inherent to the output drivers. Slower transitions can reduce high-frequency emissions and ringing on long harnesses, while the faster setting supports the upper stated CAN data rate. The selected operating mode must therefore be matched to the configured network bit rate and the physical bus characteristics. The transceiver is designed for controller-centered architectures in which a CAN controller manages arbitration, frame handling, error detection, and bus arbitration. Typical uses include industrial automation equipment, automotive electronics, building automation, robotics, embedded control systems, and other CAN networks operating at 125 kbaud or 500 kbaud. In a typical design, the L9615D sits between a microcontroller or dedicated CAN controller and the CANH/CANL pair. External network termination, common-mode choke selection, transceiver supply decoupling, and protection-device coordination remain important board-level considerations. Designers should verify the absolute maximum ratings, recommended operating conditions, pin configuration, and application circuit in the official STMicroelectronics documentation before layout release. Because the supplied search data does not expose the complete official pin table or the package drawing, this page does not infer individual pin names. It also avoids claiming undocumented electrical thresholds. The verified starting price is US$0.5310 as of 2026-10-28. This page combines verified manufacturer descriptions, distributor package and availability information, ISO/DIS 11898 and 500 kbaud operating details, and engineering-focused selection guidance.

L9615D013TR - 500 kbaud CAN Transceiver | STMicroelectronics

The STMicroelectronics L9615D013TR is a single-channel CAN bus transceiver designed for bidirectional signal conditioning between a CAN controller and a twisted-pair CAN network. It supports data rates up to 500 kbaud from a 4.5 V to 5.5 V supply and is packaged in an 8-pin SOIC. The device provides one transmitter and one receiver, differential bus outputs, short-circuit protection, and shutdown detection. A CAN transceiver is an interface IC that converts logic-level transmit and receive signals into the differential voltages carried by a CAN bus. Its position in the hierarchy is CAN transceiver → CAN interface IC → interface integrated circuit → semiconductor. Unlike a physical-layer transformer or an isolated digital transceiver, the L9615 connects a controller directly to the bus while adding the driver, receiver, protection, and biasing functions required for reliable automotive or industrial communication. Key characteristics include operation up to 500 kbaud, conformance with ISO/DIS 11898, a 4.5 V to 5.5 V supply range, and short-circuit protection for bus outputs exposed to voltages up to 36 V. Slope control reduces radio-frequency interference during transitions. The half-rate CANH and CANL bus arrangement operates from a single transceiver perspective, while the package provides a compact surface-mount footprint for control modules and electronic control units. Internally, the transmitter converts a logic-level input into a dominant differential output across CANH and CANL. The receiver interprets the differential bus voltage and presents a logic-level output to the CAN controller. The transceiver also manages the recessive state, bus biasing, fault detection, and output-stage protection. Because the L9615 is a non-isolated device, its ground reference must be compatible with the controller and the rest of the CAN node. Typical applications include automotive body and comfort modules, industrial automation controllers, elevator systems, building-automation equipment, and embedded CAN gateways. It is particularly useful where a classic 500 kbaud CAN network is used instead of a higher-bandwidth CAN FD controller. The 8-SOIC package also makes the device suitable for designs that already use conventional surface-mount PCB assembly processes. When laying out the PCB, place the transceiver close to the bus connector and keep the CANH and CANL traces as a short, closely coupled pair. Provide the supply decoupling recommended in the manufacturer datasheet, and verify the controller transceiver logic levels and termination arrangement before layout release. The operating temperature range indicated for this ordering code is -40 °C to 110 °C.

An automotive bus transceiver is an interface integrated circuit that combines bus-driver and receiver functions with the electrical protection and signal conditioning required to connect a host controller to a vehicle network. The L9637 belongs to the broader ISO 9141 interface transceiver hierarchy, where automotive diagnostics, K-line communication, and bidirectional serial links are the primary application domains. Key features include standard ISO 9141-compatible interface functions, bidirectional serial communication, reverse-battery protection, and a wide operating supply range. The monolithic design reduces the number of discrete components associated with a vehicle diagnostic interface. Its 8-pin SOIC format also supports compact surface-mount layouts and automated electronic assembly. The L9637 is intended for bidirectional communication between an automotive diagnostic tool, ECU, or other K-line interface and its associated controller. A 4.5 V minimum operating supply permits use in 5 V-class electronic systems, while operation up to 36 V provides headroom for automotive load-dump environments. The specified 40 V transient capability and -24 V reverse-supply protection are particularly important in vehicle electrical systems where wiring transients and accidental battery reversal can occur. Typical applications include ISO 9141 diagnostic interfaces, automotive ECU test equipment, bidirectional K-line links, vehicle communication modules, and service-bus diagnostic systems. The device is also suitable for industrial communication equipment that must reproduce an ISO 9141 bus interface. System-level suitability still depends on the exact bus waveform, bus speed, external resistors, connector protection, and ECU timing implemented around the transceiver. For PCB design, keep the bus connection and supply-return paths short, follow the manufacturer application schematic for external components, and place protection structures close to the vehicle connector. Designers should verify transient, ground-offset, and reverse-polarity conditions at the system level rather than relying only on the IC ratings.

Reverse-supply protection extends to -24 V, while transient operation reaches 40 V, making the interface appropriate for electrically demanding vehicle diagnostic networks. The device is used in ISO 9141 K-line diagnostic systems, automotive diagnostic testers, ECU test equipment, vehicle interface adapters, service-bus analyzers, and embedded diagnostic controllers. Its logic input and logic output arrangement allows a microcontroller UART to control and monitor communication with a vehicle ECU over the K line. When designing the circuit, protect the K-line connection against sustained faults and electrostatic discharge, place the bus-side interface components close to the connector, and verify that the external protection network does not distort the intended bus waveform. The 8-pin SOIC footprint is straightforward to route, but the connector-side transient path and ground return deserve particular attention in automotive harnesses. This page consolidates the device function, electrical limits, package details, drop-in alternatives, application guidance, and design considerations engineers need when selecting or integrating an ISO 9141 interface. It also distinguishes the target order code from related L9637 variants so engineers can verify packaging and temperature identifiers before placing a replacement on an existing PCB.

L9638D - LIN Bus Transceiver, 20 kbaud, 26 V | STMicroelectronics

The STMicroelectronics L9638D is a single-wire LIN bus transceiver rated for data rates up to 20 kbaud, with an operating supply voltage range of 6 V to 26 V and 40 V transient withstand, supplied in an 8-pin SOIC (8SO) surface-mount package. It integrates the physical layer of the Local Interconnect Network, exposing a CMOS-compatible TXD input, an RXD output to the host microcontroller, a hardware enable input, and a single bidirectional LIN bus line. A LIN transceiver is a dedicated interface IC that connects a microcontroller's protocol handler to the physical bus wiring of a vehicle. In the hierarchy of electronics, a LIN transceiver belongs to the interface IC family, alongside CAN, RS-232 and RS-485 transceivers, and is a physical-layer building block for in-vehicle distributed power and control networks. LIN is a single-wire, low-cost, low-bitrate serial bus standardized for body electronics and comfort systems. Key features of the L9638D include conformance to the LIN specification revision 2.0, compatibility with standard ISO 9141 systems, operation down to 6 V for battery-connected 12 V systems, a very low typ. 10 microamp sleep quiescent current, wake-up through the LIN bus line, and an enable input driven directly from a microcontroller CMOS output. Technically the device is a monolithic integrated circuit that combines a bus driver and receiver with control logic for power-saving modes and external wake-up handling. Because the LIN bus is a single wire referenced to ground, the transceiver provides the dominant/ recessive level conversion, bus biasing and bus-recessive detection that the protocol handler requires, while the host microcontroller handles framing, checksums and timing. Typical applications include body control modules, door and tailgate modules, climate control units, ambient light and seat-occupancy sensor nodes, window lift controllers, and other LIN-attached automotive sub-systems where a low-cost single-wire network replaces point-to-point wiring. When designing with the L9638D, place the bus line connection and its pull-up resistor close to the device, keep the LIN trace away from switching nodes, and verify supply decoupling for the 6 V to 26 V operating range, including the 40 V transient condition present on automotive battery lines. The sleep current of 10 microamp typ. supports dark-current-sensitive parked vehicles.
