MC3403DG

MC3403DG - Quad 1MHz Op Amp, 3-36V | onsemi

onsemi MC3403DG is a quad general-purpose operational amplifier with true differential inputs, a 3 V to 36 V supply range, 1 MHz gain-bandwidth product, and a 14-pin SOIC package. It provides four amplifiers in one package and is designed for single-supply signal-conditioning, buffering, filtering, current-sensing, analog measurement, and precision-control circuits. An operational amplifier, or op amp, is a voltage-amplified differential building block whose open-loop gain falls with frequency. The MC3403 family belongs to the broader hierarchy of analog amplifier ICs used to amplify small differential signals, buffer high-impedance sources, implement active filters, and close feedback loops around sensors or actuators. Its true differential inputs make the device particularly useful when a useful output must follow the difference between two input voltages rather than either input alone. The quad configuration provides four amplifiers in one 14-pin SOIC, reducing board area and simplifying multi-channel designs. Key characteristics include operation from 3 V to 36 V, a 1 MHz gain-bandwidth product, and a maximum input offset voltage of 10 mV as listed by Mouser. The part is identified as a standard general-purpose amplifier and is suitable for instrumentation, buffer-amplifier, measurement, filtering, and precision-control applications. Its single-supply capability is particularly useful in cost-sensitive systems where one supply rail must support the complete analog signal chain. Differential inputs allow subtraction, current-loop monitoring, sensing across resistive elements, and amplification of sensor outputs without external input networks. Because the package contains four amplifiers, designers can use matched functional channels for simultaneous acquisition, multi-axis sensing, or multiple filter stages while preserving consistent board organization. Typical uses include 4-20 mA process-control inputs, resistive sensor conditioning, active low-pass or band-pass filters, buffered sensor outputs, general-purpose instrumentation, and current-shunt measurements. The 3 V minimum supply supports modern 3.3 V systems, while the 36 V maximum provides additional headroom for industrial supply rails. Commercial-temperature operation is identified in distributor listings, although the exact temperature limits require confirmation from the manufacturer datasheet. When laying out a MC3403DG circuit, place input, feedback, and compensation components close to the relevant SOIC pins and provide adequate return paths for each amplifier channel. Decoupling capacitors should connect between the supply pins and ground with short traces, and unused amplifier inputs should be tied to a defined potential rather than left floating. Check output-current, input-common-mode, noise, and stability requirements against the complete operating conditions before finalizing the design. This product page combines verified manufacturer and distributor information, a complete 14-pin pinout, practical single-supply design guidance, and a parameter-based comparison with available 14-pin quad amplifier alternatives. It also distinguishes confirmed electrical characteristics from parameters that still require verification in the manufacturer datasheet.

MC3403DR

MC3403DR - Quad 30 V 1 MHz Op Amp | Texas Instruments (Tape & Reel)

The Texas Instruments MC3403DR is a quad, general-purpose bipolar operational amplifier built for single-supply and dual-supply analog systems. The device provides four amplifiers in a 14-SOIC package, operates from ±2.5 V to ±15 V according to the cited distributor specification, and supports a 1 MHz gain-bandwidth product. Its four-circuit integration reduces package count while providing true differential inputs and push-pull output capability. What is a quad operational amplifier? A quad operational amplifier combines four independent amplifier sections in one IC. These amplifiers serve as the active gain elements in sensors, buffers, analog filters, comparators, and feedback-control circuits. The MC3403 belongs to the operational-amplifier hierarchy, which is part of the broader amplifier-IC and signal-conditioning categories used in industrial control, instrumentation, audio, and communications equipment. Key verified features include four amplifier circuits, 1 MHz operation, 0.6 V/µs slew rate, a 14-pin SOIC package, and operation from −25 °C to 85 °C. The push-pull output stage supports bidirectional output-current drive in suitable loads, while the quad configuration gives designers four reusable analog channels in one package. These attributes make the MC3403DR practical for low-to-moderate-frequency analog signal paths where four similar amplifier functions are required. The MC3403’s electrical characteristics are described as similar to the popular UA741 family, but its architecture is specifically useful in single-supply applications. Compared with a basic dual-supply-only op amp, the part offers a practical path to operating from a single rail in many circuits. Designers must still check input common-mode limits, output swing, supply current, noise, offset behavior, and stability against the manufacturer datasheet for the exact operating condition. Typical uses include sensor buffering, low-frequency active filtering, audio preamplification, transducers, analog control loops, and general instrumentation. For a new design, confirm the required input and output voltage ranges, acceptable slew rate, load impedance, noise performance, and temperature limits. For a replacement, verify the exact pinout, supply range, common-mode range, and output-swing requirements rather than relying only on the amplifier count. A key practical consideration is decoupling. Place the required supply bypass capacitors close to the power pins and keep sensitive input and feedback traces short. The MC3403DR is a general-purpose amplifier, not a precision or high-speed device; use a more specialized amplifier when low offset, low noise, high speed, rail-to-rail operation, or extended temperature performance is mandatory. This page consolidates verified manufacturer and distributor information, drop-in alternatives, application guidance, package details, and selection considerations for engineers evaluating MC3403DR. It is intended to support procurement and design review without substituting unsupported specifications for missing datasheet data.

MC3403DT

MC3403DT - Quad 36V 1MHz Op Amp IC | STMicroelectronics

The STMicroelectronics MC3403DT is a low-cost, low-power quad bipolar operational amplifier with four true differential amplifier sections, a 1 MHz gain-bandwidth product, and single-supply operation from 3 V to 36 V. The device is packaged in a 14-pin SOIC and can also operate from dual supplies of ±18 V. Its short-circuit-protected outputs, internally compensated Class AB output stages, and input bias current of 500 nA maximum make it suitable for general-purpose analog signal conditioning. An operational amplifier is an amplifier IC that compares two input voltages and drives its output to represent their difference. A differential input stage rejects common-mode signals, while internal frequency compensation simplifies closed-loop design. The MC3403 combines four amplifiers in one package, placing it in the hierarchy of quad op amp, operational amplifier, analog amplifier IC, and semiconductor. Its broad supply range also makes it a bridge between classic 741-class circuitry and newer low-voltage single-supply systems. Key features include four independent amplifier channels, true differential inputs, 1 MHz gain-bandwidth performance, operation down to a 3 V single supply, and operation up to a 36 V single supply. Each output stage uses a Class AB topology for reduced crossover distortion, while short-circuit protection improves robustness when an output is driven into a difficult load. The internally compensated design supports direct use as a voltage follower or noninverting amplifier without external frequency-compensation components. The MC3403 family combines the general-purpose behavior of the UA741 with lower supply-current demand and improved suitability for single-supply operation. Each channel presents differential inputs, allowing signals to be referenced around the supply midpoint in single-supply circuits. Because the amplifiers are not rail-to-rail, input and output common-mode limits remain important when the signal approaches either supply rail. Designers should use the manufacturer data sheet for exact electrical limits, input-offset voltage, slew rate, output-current capability, and channel-matching characteristics. Typical uses include sensor-signal conditioning, low-frequency active filters, instrumentation amplifiers, audio preamplifiers, transducers, analog control loops, and general instrumentation. Four amplifiers in one package can implement a complete filter, multi-stage gain block, comparator-style signal conditioning, or several independent channels when board area and component count are priorities. The SOIC-14 package also supports conventional through-hole PCB assembly rather than requiring a fine-pitch surface-mount land pattern. When designing around the MC3403DT, begin with the required input and output common-mode range at the actual supply voltage. Place supply-bypass capacitors near the device, maintain a stable reference point for single-supply signals, and verify stability for the selected gain, load, and feedback network. Avoid relying on rail-to-rail operation, and check the maximum total supply voltage when combining bipolar or dual-supply systems. This product page combines the manufacturer operating limits, package information, sourcing details, pin-level guidance, drop-in comparison criteria, and practical circuit considerations into one engineering reference. It also identifies where a new design should remain with the MC3403 family and where a lower-voltage or differently characterized amplifier offers a better fit.

MC3403N

MC3403N - Quad 30V 1MHz Op Amp | Texas Instruments

The Texas Instruments MC3403N is a quad general-purpose operational amplifier built for single- and dual-supply systems, with four amplifiers, a 30 V maximum supply rating, 1 MHz typical gain-bandwidth product, and operation from -25°C to 85°C. It is supplied in a 14-pin PDIP package. An operational amplifier is an analog integrated circuit that uses high-gain differential feedback to amplify the difference between two input voltages. The MC3403 belongs to the broader amplifier hierarchy: operational amplifier, analog IC, semiconductor, and general-purpose signal-conditioning component. Its quad construction reduces package count when a design needs several independent gain stages, buffers, or comparators. The verified product information identifies wide supply-voltage support, a true differential input stage, internal frequency compensation, low input bias current, a Class AB output stage, and short-circuit protection. The 1 MHz gain-bandwidth product is suitable for general-purpose audio, control, and instrumentation circuits rather than precision or high-speed applications. Because all four amplifiers share one package, supply pins and exposed signal pins must be routed carefully on mixed analog and digital boards. The 30 V supply capability permits operation from conventional single supplies or split dual supplies, making the device useful in legacy industrial, audio, and control designs. However, exact input common-mode limits, output swing, input offset voltage, supply-current, noise, and slew-rate values are not stated in the supplied verified excerpts; those parameters require confirmation in the manufacturer datasheet before final circuit sign-off. Typical applications include four-channel audio preamplification, low-frequency active filtering, sensor-signal conditioning, industrial control loops, and general buffer or gain stages. In each case, the 1 MHz bandwidth should be compared with the closed-loop gain and required settling behavior. A four-amplifier package can reduce board area, but it does not eliminate the need to check common-mode range, output swing, stability, and supply-decoupling requirements at every amplifier section. Design with a local bypass capacitor near the supply pins, maintain the required input common-mode range, and verify output-voltage headroom under the intended load. Do not infer precision performance from the word general-purpose. This product page consolidates the verified manufacturer identity, distributor listing, package, temperature range, supply rating, and replacement research while explicitly marking unavailable detailed electrical parameters. The alternatives listed here are limited to candidates supported by the supplied cross-reference data and are presented as package-compatible engineering options; final qualification should confirm pinout, supply limits, input/output ranges, offset, bandwidth, slew rate, and lifecycle status against the selected manufacturer datasheet.

MC3403NS

MC3403NS - Quad 30V 1MHz Op Amp | Texas Instruments

Texas Instruments MC3403NS is a quad general-purpose operational amplifier rated for 30 V supply operation, 1 MHz gain-bandwidth product, and operation from -25°C to 85°C. The device is offered in a 14-pin SOIC package and contains four amplifiers, each with a Class AB output stage, true differential inputs, and internal frequency compensation. It supports single-supply operation from 3 V to 36 V or dual-supply operation, making it suitable for industrial control, instrumentation, audio, and signal-conditioning systems. An operational amplifier is an analog signal-processing IC that compares an inverting input with a non-inverting input and amplifies the voltage difference between them. Operational amplifiers belong to the amplifier IC hierarchy, combining high open-loop gain, negative feedback, signal amplification, filtering, buffering, and active transducer conditioning. Their internal frequency compensation removes the need for an external dominant-pole capacitor in ordinary closed-loop applications. The MC3403NS provides four low-power amplifiers in one package, reducing board area compared with discrete single or dual amplifier implementations. Its low input bias current is useful when the source impedance is relatively high, while short-circuit protection improves robustness in feedback-controlled circuits. The 30 V rating and wide supply range support legacy industrial systems operating from higher-voltage rails than typical modern 3.3 V or 5 V analog circuits. Technically, each channel uses a true differential input stage and a Class AB output stage. Internal frequency compensation supports stable operation in standard closed-loop configurations, including inverting and non-inverting amplifiers. The 1 MHz gain-bandwidth product limits closed-loop bandwidth according to the selected noise gain, so higher gain reduces usable bandwidth. The wide common supply range also allows ±15 V dual-supply operation in legacy analog systems. Typical uses include four-channel sensor conditioning, general-purpose voltage amplification, audio preamplification, active filtering, data acquisition front ends, and industrial control interfaces. Multiple independent channels can process several low-frequency signals while sharing one supply and package. Where source impedance is high, input bias current and offset characteristics should be checked before selecting the amplifier. A primary design consideration is rail headroom. The output cannot swing fully to either supply rail, and single-supply designs must include sufficient voltage at the output for the downstream load. Place bypass capacitors close to the supply pins, keep feedback loops compact, and verify stability, output swing, and input common-mode range across temperature. This page combines the manufacturer specifications with package guidance, practical circuit considerations, comparison criteria, and sourcing information for engineers evaluating the MC3403NS. The technical guidance emphasizes how its 30 V supply capability, 1 MHz bandwidth, four-channel integration, and 14-pin SOIC footprint affect replacement and design decisions.

MC3403P

MC3403P - Quad 36V 1MHz Operational Amplifier | onsemi

The onsemi MC3403P is a low-cost quad operational amplifier with true differential inputs, internally compensated operation, and a 14-pin plastic DIP package. It contains four amplifiers in one package and operates from a single supply or from split dual supplies, with a maximum single-supply rating of 36 V corresponding to dual operation up to ±18 V. Its 1 MHz gain-bandwidth product supports general-purpose signal conditioning at frequencies up to 1 MHz. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. The MC3403 belongs to the general-purpose bipolar operational-amplifier family within the broader amplifier IC and semiconductor hierarchy. Unlike circuits built around the classic UA741, the MC3403 was designed with practical single-supply operation in mind. True differential inputs also allow the amplifier to reject common-mode signals when suitable feedback networks and operating conditions are used. The MC3403P provides internally compensated amplifiers, short-circuit-protected outputs, and a Class AB output stage designed for minimal crossover distortion. Maximum input bias current is specified at 500 nA, making the device practical for higher-impedance sensing paths when leakage and bias-current errors are controlled. Its internally compensated architecture removes the need for an external compensation capacitor in the standard closed-loop configurations shown in typical applications. Each of the four amplifier sections supports common inverting, non-inverting, summing, and difference-amplifier arrangements. The 1 MHz gain-bandwidth product means bandwidth decreases as closed-loop gain increases; designers should therefore account for gain-bandwidth behavior when targeting precision, pulse, or audio-frequency signals. The 36 V maximum supply also provides ample headroom for industrial and educational circuits, although the actual common-mode and output-swing limits must be observed at lower supply voltages. Typical uses include low-frequency audio amplification, active filtering, sensor signal conditioning, waveform generation, and general instrumentation. The four independent amplifiers can implement a complete signal chain in one package, reducing board space compared with four separate single or dual amplifier ICs. In AC-coupled audio and instrumentation circuits, input and feedback components can be selected around the required gain and bandwidth rather than relying on a fixed internal compensation network. Designers should verify the MC3403P pinout before PCB assembly and observe the datasheet limits for input voltage, common-mode range, output swing, supply current, and temperature. A stable bypass capacitor near the supply pins is advisable, and the unused amplifier sections should be configured according to the manufacturer’s recommended practice rather than left floating. Because this is a through-hole DIP device, insertion and soldering require adequate clearance around the package and between adjacent board components. This product record combines verified manufacturer and distributor information, same-footprint alternatives, package and pinout details, and practical selection guidance. It is intended to help engineers identify the MC3403P quickly for legacy industrial, audio, education, and prototype designs while making package constraints and replacement limits explicit.

An operational amplifier is an analog signal-conditioning IC used to amplify voltage differences, buffer sensor outputs, and support feedback-control networks. The MC3403 belongs to the operational-amplifier hierarchy, which includes differential-input amplifiers, analog amplifiers, and integrated analog ICs. Its four amplifiers can perform independent signal-conditioning functions while sharing one package and supply connection. The principal features of the MC3403PG include four internally compensated operational-amplifier circuits, true differential inputs, a 1 MHz gain-bandwidth product, a 0.6 V/us slew rate, and operation from a single supply as low as 3 V or as high as 36 V. The electrical characteristics are similar to the popular MC1741C, but the MC3403 adds the advantages required in modern single-supply circuitry. Split-supply operation is also possible when the total voltage between the supply terminals remains within the device's operating range. Because this is a general-purpose amplifier rather than a precision or rail-to-rail part, the input common-mode range, output swing, offset voltage, and stability behavior should be checked against the actual signal and load before final circuit approval. Typical uses include four-channel sensor conditioning, low-frequency active filters, audio preamplification, transducer interfaces, general feedback-control loops, and instrumentation. The 14-DIP format is particularly suitable for through-hole prototypes, educational equipment, legacy control boards, and industrial assemblies where a through-hole quad amplifier simplifies socketed construction and servicing. When laying out a MC3403PG circuit, connect each amplifier's supply pins to the same supply network and place suitable bypassing capacitance close to those pins. Keep sensitive input routing away from high-current switching nodes, and verify that the selected feedback network remains stable with the actual source impedance and load capacitance. This product record combines the MC3403PG specifications, package information, sourcing guidance, candidate replacements, and application-oriented design notes in one place. The comparison tables and selection guidance help engineers distinguish true same-package alternatives from devices that would require board or signal-chain changes.

The device is packaged in a 14-pin TSSOP, making MC3403PW suitable for compact analog signal-processing circuits that require four amplifiers in one package. An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its two inputs while providing high input impedance, low output impedance, and stable operation with feedback. The MC3403 family combines four amplifiers with a low-power class AB output stage, true differential inputs, internal frequency compensation, and short-circuit protection. It sits within the operational-amplifier category as a general-purpose amplifier for instrumentation, control, and signal-conditioning systems. Key characteristics include four independent amplifier channels, a 1 MHz gain-bandwidth product, support for single and dual supplies, a true differential input stage, and internal frequency compensation. The -25°C to 85°C operating-temperature range supports industrial and commercial equipment when the surrounding system provides suitable thermal conditions. Its 14-pin TSSOP also reduces board area compared with four separate single-amplifier packages. Each amplifier is frequency compensated, so applications using voltage gain do not require an external compensation network. The class AB output stage is designed to support linear operation while the short-circuit-protection feature improves resilience in feedback-controlled circuits. Because the device is intended for general-purpose signal amplification, external precision resistors, compensation, output isolation, and protection components may still be needed when driving loads, extending bandwidth, or meeting application-specific noise and accuracy targets. Typical uses include low-frequency sensor conditioning, feedback-control loops, current-voltage signal conversion, analog summing and difference circuits, and four-channel buffer arrangements. The integrated quad structure is especially useful where several independent analog paths must fit on a compact PCB, such as industrial measurement modules, instrumentation interfaces, and embedded control systems. PCB layout should keep feedback resistors close to their corresponding amplifier pins, provide a solid ground return, and route high-impedance input nodes away from switching nodes. Decoupling capacitors should be placed close to the supply pins. Designers should verify output swing, input common-mode range, load capability, stability, and supply limits for the intended operating points using the manufacturer datasheet. This page combines the manufacturer product information, distributor product records, package details, application guidance, and available same-footprint comparison information to support component selection and board-level planning.

MC34071D

MC34071D - 44V Single-Supply Operational Amplifier | onsemi

The onsemi MC34071D is a single-supply operational amplifier designed for operation from 3.0 V to 44 V, with a 4.5 MHz gain-bandwidth product and a 13 V/µs slew rate. The device is packaged in an 8-pin SOIC and uses bipolar fabrication rather than JFET input devices. Its combination of high bandwidth, fast slew rate, and a wide supply-voltage range makes it suitable for industrial instrumentation, signal conditioning, data acquisition, and control systems that operate from elevated supply voltages. An operational amplifier is a high-gain differential amplifier used to amplify small input signals, buffer sensors, drive analog stages, and implement feedback-control networks. The MC34071 belongs to the broader hierarchy of operational amplifier, analog amplifier, signal-conditioning IC, and semiconductor. Although the MC34071 family can operate from split supplies, it is particularly suited to single-supply operation, which simplifies circuits whose signal reference is close to the lower supply rail. The family provides 4.5 MHz of gain-bandwidth product, a 13 V/µs slew rate, and fast settling time without using JFET device technology. The specified single-supply performance is defined at 5.0 V. The amplifiers are also functional at 3.0 V at 25°C, although bandwidth, slew rate, DC gain, and other parameters may change in that operating region. This distinction is important when designing at the minimum supply voltage. The bipolar process supports operation from a single 5.0 V supply or higher while accommodating input and output signals referenced toward ground. The wide 44 V maximum supply rating provides additional operating headroom for industrial systems while retaining the usual bipolar advantages of low input-voltage noise and accurate behavior around the output operating point. Designers should still use the manufacturer datasheet limits for input common-mode range, output swing, supply current, and stability with the selected gain and load. Typical uses include sensor-interface amplifiers, low-side current measurement, industrial control loops, audio and communications signal conditioning, active filtering, and general-purpose analog processing. Because the amplifier is optimized for single-supply operation, input and output signal levels must remain inside the datasheet common-mode and output-swing limits. Input common-mode limits depend on supply voltage and gain, so a signal that is valid at 5 V may not remain valid at 3 V. The main design consideration is supply headroom. Use decoupling close to the supply pins, verify that the selected feedback network remains stable at the intended noise gain, and check output-current capability for the load and output-voltage conditions. The MC34071 is not intended to replace a rail-to-rail input or output amplifier where signals exceed its specified common-mode or swing limits. This page combines verified manufacturer and distributor information with practical selection criteria, sourcing guidance, and verified same-package alternatives. It highlights where the MC34071D fits, where its non-rail-to-rail architecture requires careful signal-range review, and which replacement MPNs should be checked against the full datasheet before substitution.

It is a general-purpose bipolar operational amplifier intended for instrumentation, buffering, signal conditioning, and control applications where a wide supply range and single-supply operation are useful. The device is specified for a 5.0 V single-supply condition while remaining functional down to 3.0 V at 25°C, although bandwidth, slew rate, and DC gain can change in that lower-voltage region. An operational amplifier is an analog integrated circuit that uses high-gain differential amplification to compare an inverting input with a non-inverting input. The MC34071P provides one amplifier circuit in an 8-DIP package, placing it within the hierarchy of operational amplifier, analog amplifier, and integrated circuit. Its single-supply capability simplifies circuits that operate from batteries, industrial control rails, test equipment, and other systems that do not provide a centered or negative supply. The MC34071P is associated with a 5 mV input offset voltage specification in distributor listings and uses quality bipolar fabrication in the onsemi MC33071, MC34071, and related family. The family includes dual and quad versions for designs that require multiple amplifier channels, but channel count and package differ when comparing those family members with the single MC34071P. The 8-DIP package is a through-hole package with a nominal 0.300-inch, 7.62 mm lead pitch, making it suitable for conventional PCB layouts and prototype boards. Typical uses include sensor signal conditioning, low-frequency active filtering, industrial instrumentation, audio and communications support circuits, and general voltage amplification. Because the amplifier can operate from a single supply, the input and output signal ranges must be checked against the supply rails. Designers should also account for input common-mode limits, output swing, bias-current effects, noise, stability, and the power dissipation produced by the selected supply voltage and load. The MC34071P is most appropriate when a through-hole single op amp is preferred and the design needs wide single-supply headroom. Its counterpart MC34071APG is the most directly identified cross-reference candidate in the available information. Before substituting any part, confirm the complete pinout, electrical limits, common-mode behavior, output swing, and stability requirements against the target circuit. This page consolidates the verified onsemi datasheet information, distributor package identification, and cross-reference findings into a practical component record. The key engineering distinction is not simply the 3.0 V to 44 V supply capability, but the combination of a single amplifier, bipolar implementation, through-hole 8-DIP construction, and the need to design the signal path around single-supply input and output limits.

The principal features of the MC34072D include 4.5 MHz gain bandwidth, 13 V/µs slew rate, 1.1 µs settling time to 0.1%, and a low 3.0 mV maximum input offset voltage for the A-suffix grade. It operates from 3.0 V to 44 V, and its input common-mode range includes the negative supply rail, which simplifies single-supply signal-chain design. Output swing extends from approximately -14.7 V to +14 V under the conditions listed by the manufacturer. The bipolar fabrication of the MC34071, MC34072, and MC34074 families supports the combination of wide bandwidth, high slew rate, and common-mode operation that extends to ground. This characteristic is particularly useful when signals remain close to the lower supply rail or when the amplifier must process bipolar sensor signals from a unipolar-powered acquisition circuit. Input bias current and noise specifications should be checked against the source impedance in the selected gain configuration. Typical uses include low-voltage sensor interfaces, industrial process-control loops, audio preamplifier stages, active filters, and general instrumentation. Its 3.0 V to 44 V operating range also makes it suitable for industrial systems that operate from a 5 V, 12 V, 24 V, or higher regulated rail. The device can be used where the required signal bandwidth remains below the amplifier's closed-loop bandwidth for the selected noise-gain setting. Designers should verify output-current capability, output-swing limits, input common-mode range, and stability at the intended gain and capacitive-load conditions. Keep feedback-loop layouts compact, place compensation or decoupling components close to the relevant pins, and avoid operating near the output-swing limits when driving low-impedance downstream loads. This page consolidates the MC34072D electrical characteristics, confirmed ordering variants, package information, and application guidance with comparison notes for engineers evaluating drop-in operational-amplifier alternatives.

The device is supplied in an 8-pin SOIC package according to the distributor product listing. An audio amplifier is an integrated circuit that accepts a low-level analog audio signal and delivers enough current and voltage to drive a speaker or another acoustic transducer. The MC34119 belongs to the Class AB amplifier category, where the output transistors conduct during the signal cycle for improved efficiency than a continuously biased Class A design. Its telephone-oriented architecture supports portable and line-powered equipment where low supply voltage and compact implementation are important. The verified feature set includes a shutdown function, a single mono output channel, and differential speaker outputs. Differential outputs are particularly useful in telephone and speakerphone designs because they increase output swing into a differentially connected transducer. The manufacturer datasheet also identifies a 2.0 V minimum supply, allowing operation from low-energy source rails. The Class AB output stage is intended to balance output capability against power consumption in compact audio systems. MC34119D applications include telephone speakerphones, compact voice terminals, intercom equipment, and other low-voltage audio products. In these systems, the amplifier converts a microphone or line-level signal into a differential drive capable of energizing a small speaker. Designers should account for the external output-coupling capacitors shown in the manufacturer application circuit when connecting a speaker, and should verify the shutdown-control polarity and timing before sequencing the device. The most important design consideration is ensuring that the supply, input signal, output network, and speaker load remain within the limits defined by the manufacturer datasheet. Because the target is a legacy low-power audio amplifier, purchasing decisions should also account for lifecycle status, stock, and long-term sourcing rather than assuming availability from an active-production family. This page consolidates the verified package, supply-voltage, amplifier-class, shutdown, and differential-output information with practical selection guidance. It also distinguishes confirmed facts from parameters that require confirmation in the original MC34119 manufacturer datasheet, helping engineers evaluate MC34119D without relying on incomplete distributor summaries.

It provides a practical solution where low supply voltage, low quiescent current, and efficient single-speaker drive are required. The available ordering information identifies the device as an NXP USA Inc. 8-PDIP mono audio amplifier. An audio amplifier IC is a semiconductor that accepts a small audio signal and delivers enough voltage and current to drive a loudspeaker or other audio transducer. A Class AB amplifier combines the low crossover distortion of class-A operation with improved efficiency compared with a continuously biased class-A stage. In the MC34119P, differential speaker outputs are intended to maximize output swing at low supply voltages, making the device especially relevant to compact telephone and communications equipment. The MC34119P operates from 2.0 V to 16 V, as documented in the retrieved manufacturer and distributor information. Its typical quiescent supply current is 2.7 mA for battery-powered designs, while shutdown reduces the typical quiescent current to 65 µA. A chip-disable input provides a direct means of placing the amplifier in its low-power state. These features allow the amplifier to remain useful when system power is constrained by a telephone line or battery source. Its architecture uses one Class AB output channel and differential speaker outputs rather than a conventional single-ended output arrangement. Differential drive can provide greater useful voltage swing into the speaker for a given supply, which is important at the 2 V minimum supply. This is a system-level advantage in speakerphone products where loudness and battery efficiency must coexist. Exact continuous output power, output impedance, gain settings, and distortion limits were not included in the retrieved source snippets and must be confirmed in the full manufacturer datasheet before final design sign-off. Typical uses include telephone speakerphones, telephone-line powered communications products, small intercom stations, compact voice monitors, and portable low-voltage audio equipment. The device is also suitable where standby consumption matters, because the shutdown function can isolate the amplifier from the active signal path. For these applications, the 2 V minimum operating voltage and differential output capability align particularly well with low-power, single-speaker systems. The primary design consideration is output-device and load compatibility. Engineers should verify speaker impedance, output power at the available supply voltage, thermal conditions, gain configuration, bypass capacitors, and shutdown logic against the complete MC34119 datasheet. Because the supplied text identifies an 8-DIP footprint but does not enumerate individual terminal functions, the pin assignment and exposed circuit details should not be inferred solely from this page. This product page consolidates the verified MC34119P package, voltage, topology, shutdown, and low-power information with practical application guidance, sourcing considerations, and honest drop-in replacement analysis. Its key value is separating confirmed MC34119P characteristics from unverified specifications and avoiding unsupported claims about substitutes that may require different EMI performance or pin behavior.

MC34184M

MC34184M - Low-Power Quad JFET Op Amp | onsemi

The onsemi MC34184M is a low-power, quad, JFET-input operational amplifier characterized by 210 uA of supply current per amplifier, a 4.0 MHz gain-bandwidth product, and a 10 V/us slew rate. Housed in onsemi's legacy MC34184M package, the device combines low input bias current with high input resistance for instrumentation, signal-conditioning, and low-frequency analog systems. A JFET-input operational amplifier is a voltage-amplifier device whose input stage uses junction field-effect transistors. This input architecture provides high input resistance and low input bias current while supporting relatively low supply-current operation. Within the power-management and analog-signal hierarchy, the MC34184M belongs to the operational-amplifier family and functions as a high-impedance buffer or closed-loop gain stage between sensors, transducers, analog switches, and downstream conversion or control circuitry. The primary performance characteristics of the MC34184M include a 4.0 MHz gain-bandwidth product, 10 V/us slew rate, and approximately 210 uA of supply current per amplifier. Its JFET input stage provides high input resistance, low input offset voltage, and high open-loop gain according to the Motorola MC34184 datasheet. These characteristics make the amplifier appropriate for precision current-voltage conversion, low-level signal amplification, active filtering, and feedback networks operating at low or moderate frequencies. The family architecture also supports practical instrumentation requirements because low input bias current reduces disturbance of high-impedance sources. A high gain-bandwidth product allows useful closed-loop bandwidth above the audio range when configured with conventional compensation and suitable external resistors. The 10 V/us slew rate improves handling of moderately fast signal edges, although the 4.0 MHz bandwidth places the device in the general-purpose precision-amplifier class rather than the high-speed operational-amplifier class. Typical applications include bridge-sensor signal conditioning, biomedical instrumentation, photodiode and phototransistor amplifiers, audio preamplification, active filters, sample-and-hold stages, and low-frequency closed-loop control loops. In each case, the amplifier should be evaluated for input common-mode range, output swing, noise, offset, stability, and supply compatibility under the actual operating conditions. Designers should verify the package dimensions, pin numbering, electrical limits, and common-mode range against the manufacturer documentation before layout. Input and feedback resistors must also be selected for low thermal noise and acceptable bias-current error. Bias compensation may be useful when source resistance is high enough that input bias current produces a material offset across the source impedance. This page organizes the core MC34184M electrical characteristics, practical application guidance, comparison parameters, and design considerations into one engineering-focused reference. It supports early architecture selection while preserving the need to verify production details, lifecycle commitments, and assembly-specific information with the manufacturer before releasing a design.

MC3437L

MC3437L - Hex Bus Receiver with Input Hysteresis | Motorola

The Motorola MC3437L is a six-channel hexadecimal bus receiver with input hysteresis, supplied in a 16-pin CDIP package. The verified distributor listings identify the device as a 0/6 receiver and indicate a listed unit price of $2.6678 at LCSC as of 2026-10-23. The receiver is intended for digital bus-interface applications where noise immunity and signal conditioning are important. A bus receiver is an interface IC that converts a digital logic signal into a cleaner, standardized receiver output. The MC3437L belongs to the receiver and transceiver category, providing six receiver channels rather than a general-purpose analog function. Input hysteresis creates a defined transition region between low and high input levels, helping prevent output chatter when a noisy or slowly changing signal crosses the logic threshold. The verified search data specifically identifies the MC3437 as a Hex Bus Receiver with Input Hysteresis. The MC3437L ordering variant is shown by DigiKey as a 0/6 Receiver in a 16-CDIP package. The available source data does not provide detailed input thresholds, propagation delays, supply-voltage limits, output levels, temperature ratings, or absolute maximum ratings, so those values are not inferred here. Typical uses include digital control buses, computer peripheral interfaces, industrial equipment, communications equipment, and legacy systems where a six-channel receiver is useful. The CDIP package supports through-hole PCB assembly and may be preferred for repair, prototyping, and systems that use conventional DIP-compatible footprints. Actual signal integrity and system compatibility require checking the original manufacturer datasheet and the host bus voltage and timing. When replacing MC3437L, verify the exact pinout, logic polarity, supply requirements, propagation delay, and input thresholds before substitution. Do not assume that a similarly named transceiver or receiver is pin-compatible. The available source data does not establish lifecycle status, detailed electrical ratings, or a verified five-part drop-in replacement set.

MC3459P

MC3459P - Quad NMOS Address Line Driver | Motorola

The Motorola MC3459P is a quad NMOS address line driver, also described as a bipolar bus driver, packaged in a 14-pin DIP. The device contains four address-driver elements, each with a one-bit output, for driving address and control lines in older digital systems. According to the available distributor and datasheet listings, the MC3459P operates from a 5.25 V supply and is categorized as an address driver, bus driver, buffer, driver, receiver, and transceiver. A bus driver is an interface IC that strengthens digital signals so they can reliably travel between circuit boards, processors, memories, and peripheral devices. Within the logic-IC hierarchy, a bus driver sits below interface ICs and above general-purpose buffers. The MC3459P is specifically intended to drive multiple address lines in systems where the source device cannot directly provide the required output current or signal integrity. The main verified characteristics are a four-element architecture, one-bit output per element, a 5.25 V supply designation, bipolar bus-driver construction, and a 14-pin DIP package. The listings also identify the device as a Quad NMOS Address Line Driver. The exact output-current rating, propagation delay, output disable levels, input and output logic levels, operating temperature range, and absolute maximum ratings are not present in the supplied search data and therefore require confirmation from the manufacturer datasheet before release to production. The 14-pin through-hole package makes the MC3459P suitable for legacy computer, industrial-control, instrumentation, and data-acquisition equipment where motherboard-level bus routing and socketed DIP construction remain practical. Its four independent driver elements can be assigned to address or control lines when the system architecture requires buffered digital outputs. Modern designs may instead favor surface-mount bus-driver ICs with documented electrical limits and lifecycle guarantees. Engineers should confirm the pinout, enable-control polarity, and logic thresholds before substitution because the supplied distributor records identify the function and package but do not provide a complete pin table. Power-supply decoupling, unused-input handling, and signal-integrity checks should follow the manufacturer datasheet rather than assumptions based on generic 14-pin bus drivers. This page combines verified distributor descriptions, package information, sourcing records, and qualification data into a structured engineering reference. It also documents the remaining datasheet-dependent parameters and the limited cross-reference evidence so that engineers can distinguish confirmed facts from data requiring validation before procurement or PCB redesign.

MC3461L

MC3461L - Dual Current Sense Amplifier | Motorola | CDIP-16

The Motorola MC3461L is a dual current-sense amplifier in a 16-pin CDIP package, with two amplifier circuits for measuring current across low-value shunt resistors. The verified distributor data identifies the device as a high-speed NMOS/MECL current-sense amplifier, while detailed electrical limits, gain values, common-mode range, supply voltage, and temperature ratings are not included in the supplied records and therefore remain unconfirmed. Its instrumentation-amplifier classification places it among amplifier ICs used for power-conversion monitoring, motor control, battery management, and power-supply feedback. A current-sense amplifier is a specialized voltage-feedback amplifier that develops a measurable output voltage from the small differential voltage created by current flowing through a shunt resistor. The MC3461L contains two circuits, allowing one packaged device to monitor two independent current paths when the circuit board has sufficient isolation and the operating conditions of both channels are compatible. The 16-CDIP mechanical format is a through-hole ceramic dual in-line package intended for legacy industrial, instrumentation, and telecommunications equipment. The MC3461L's two-circuit architecture reduces component count compared with two separate single amplifiers, while its small shunt-generated differential signal supports compact sensing layouts. However, stable measurement depends on selecting an appropriate shunt, keeping Kelvin connections narrow and symmetrical, and observing the amplifier's common-mode and output limits. Because those numerical limits are absent from the verified excerpts, designers should consult the complete manufacturer datasheet before finalizing resistor values, gain configuration, supply rails, or production tolerances. The MC3461L is suitable for power-supply current monitoring, battery charge and discharge sensing, motor-control feedback, industrial process-control systems, and communications equipment. In these applications, the amplifier converts bidirectional or unidirectional shunt current into a voltage suitable for an ADC, controller, comparator, or protection circuit. The exact input polarity, output reference arrangement, and permissible common-mode voltage must be verified from the full datasheet before layout sign-off. A practical design begins by placing the shunt and amplifier in the same high-current path, routing the sense traces as a tightly coupled differential pair, and grounding the unused inputs or amplifier according to the manufacturer's recommended configuration. Decoupling capacitors should connect directly to the supply pins, and the output must remain within the device's verified output range. PCB creepage, clearance, copper heating, and Kelvin-trace geometry are as important as the IC choice in a high-current design. This page combines verified distributor identity and availability information with clearly marked engineering gaps, practical application context, and design guidance. It does not infer missing electrical specifications from the MC3461 family name, so procurement, electrical, and package decisions should be completed against the official datasheet and current authorized-channel inventory.

MC3476P1

MC3476P1 Low-Cost Programmable Operational Amplifier | onsemi

The onsemi MC3476P1 is a low-cost, programmable operational amplifier designed for general-purpose analog signal conditioning. The device is associated with an 8-pin DIP package, and its core features include low power consumption, high input impedance, and a programmable operating point that allows engineers to adapt the amplifier to different bias and performance requirements. The MC3476P1 is therefore useful in applications requiring adjustable amplifier behavior rather than a fixed, conventional op-amp configuration. An operational amplifier is a voltage-controlled differential amplifier with very high open-loop gain. Its two inputs are the inverting input and non-inverting input, while the output is controlled by feedback in most practical circuits. The programmable family represented by the MC3476P1 adds a bias-current control function, allowing the operating current and associated performance to be adjusted externally. This makes the device more flexible than a fixed-bias amplifier when system designers need to balance power consumption, bandwidth, output drive, and signal-source loading. The MC3476P1 is described by its manufacturer as a low-cost selection of the MC1776 programmable operational-amplifier family. Its low power consumption is useful in battery-powered, portable, and low-power instrumentation systems. High input impedance helps reduce loading on high-impedance signal sources, which can help preserve signal amplitude and reduce input-stage interaction. The programmable bias architecture also gives designers a way to tailor performance after considering source impedance, gain, bandwidth, and acceptable supply current. Typical analog uses include sensor-interface stages, low-frequency instrumentation, buffer and gain stages, active filters, and signal-conditioning blocks in industrial or embedded control systems. The device can be used where a general-purpose amplifier is sufficient and adjustable operating current is valuable. Designers should review the manufacturer datasheet for guaranteed input-voltage range, output-swing limits, supply-current ranges, gain-bandwidth behavior, offset voltage, input bias current, and package details before finalizing a design. A key implementation consideration is the connection of the programmable-bias circuitry. Incorrect resistor values, unsuitable bypassing, or operation outside the specified supply and common-mode ranges can reduce stability or prevent expected output behavior. Keep the input network and feedback components close to the device, use a stable bypass capacitor at the supply pins, and verify noise, settling time, and output-swing requirements with the actual source impedance and load. This page combines the manufacturer-linked product identity, documented package information, application guidance, and practical design considerations for engineers evaluating the MC3476P1. Because the exact electrical limits and pin assignments are not reproduced in the cited search results, consult the original MC3476P1 datasheet for authoritative values before schematic release, PCB layout, or production qualification.

MC3487D

MC3487D - 4-Channel RS-422 Driver | Texas Instruments | 5V

The Texas Instruments MC3487D is a quadruple differential line driver with four independent drivers, a 5 V single supply, and a 16-pin SOIC package. Its differential outputs meet ANSI TIA/EIA-422-B and ITU Recommendation V.11 requirements, while the tri-state outputs permit a high-impedance state for bus management. Each channel uses a TTL-compatible buffered input to reduce loading, making the device suitable for RS-422 point-to-point and multidrop communications. A differential line driver is an interface IC that converts a single-ended logic signal into a balanced pair of differential signals. In the hierarchy of electronic components, it belongs to the interface IC family, within communication and transceiver devices. Differential signaling improves noise immunity by rejecting common-mode noise and allows reliable data transmission over longer cable runs than ordinary single-ended digital logic. The MC3487D provides four driver channels rather than a full transceiver, so it does not receive differential data. The output-enable function controls the output state, allowing connected drivers to be disabled when they are not active. This is useful in systems that share a bus or require controlled output states. Power-up and power-down protection are also identified in the manufacturer documentation. Typical uses include industrial RS-422 links, data acquisition systems, test equipment, instrumentation, and multi-channel communication links. The 5 V supply operation simplifies interface design in legacy and industrial systems where the host logic uses a 5 V rail. Because it is a driver-only device, the system designer must provide the receiving circuitry and define cable termination, grounding, and enable-control behavior. The main design considerations are signal integrity, cable length, supply decoupling, and output-state control. Differential pairs should be routed with consistent geometry and appropriate grounding. The output-enable signals should be controlled during reset so that multiple channels do not contend on a shared bus. The device is intended for surface-mount assembly in the 16-pin SOIC package.
