MC3403D 概要
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 MC3403D 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 MC3403D 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.

主な用途
MC3403D の用途: 6 件s: Sensor Signal Conditioning, Audio Preamplification, Active Filtering, Industrial Control Loops, Transducer and Bridge Interfaces, Test and Measurement Front Ends.
Sensor Signal Conditioning
The MC3403D is suitable for buffering and amplifying outputs from sensors such as resistive bridges, temperature elements, and low-level analog transducers. Its four-amplifier arrangement allows several conditioning channels to share one 14-SOIC package, while the verified 1 MHz gain-bandwidth product supports signal paths below the amplifier’s higher-frequency limits. True differential inputs are useful when the source has a differential signal. The design must verify input common-mode range, input bias current, output swing, and noise from the manufacturer datasheet before selecting resistor values or fault thresholds.
おすすめ
Audio Preamplification
MC3403D can provide modest-bandwidth audio preamplification for line-level or instrument signals when its verified 1 MHz bandwidth and 0.6 V/µs slew rate are adequate. Four channels allow stereo or multi-channel preamplification to be consolidated in one 14-SOIC package. The device is not presented in the supplied data as a low-noise audio amplifier, so input-referred noise and offset must be checked before using it in a high-fidelity signal chain. Keep the output within the specified swing and provide stable feedback compensation for the selected gain.
おすすめ
Active Filtering
The MC3403D is applicable to first- and second-order active-filter stages operating at low or moderate frequencies. The verified 1 MHz gain-bandwidth figure and 0.6 V/µs slew rate provide useful design context for determining whether the amplifier can support the intended closed-loop gain and transient response. Four amplifiers can implement multiple filter sections without using four separate packages. Verify open-loop gain, noise gain, stability, and output-current limits in the datasheet because those values were not supplied in the verified source snippets.
おすすめ
Industrial Control Loops
The four amplifier channels can be used in industrial control and instrumentation circuits for error amplification, actuator-driver interfaces, and feedback summing. The MC3403D’s general-purpose bipolar architecture, true differential inputs, and single-supply usability make it a practical fit for nonprecision analog control blocks. The verified operating temperature range is −25 °C to 85 °C, which is narrower than many industrial requirements. Confirm environmental limits, supply tolerances, noise, and output-drive requirements before deploying it in a factory or process-control system.
おすすめ
Transducer and Bridge Interfaces
MC3403D is suitable for analog interfaces that need differential excitation, amplification, and buffering around resistive sensors. The true differential input architecture can simplify conditioning of bridge-like or balanced sensor outputs, while four channels allow instrumentation, gain, filtering, and output stages to be grouped. The verified data does not provide input offset, bias current, noise, or common-mode values, so those parameters must be checked from the manufacturer datasheet. Keep sensor excitation and signal-ground paths separated appropriately to avoid corrupting small differential signals.
おすすめ
Test and Measurement Front Ends
The MC3403D can serve as a general-purpose front-end amplifier in test and measurement equipment when low frequency, moderate bandwidth, and multi-channel analog conditioning are sufficient. Its quad architecture helps reduce the number of amplifier packages in a multi-range instrument. The verified 1 MHz gain-bandwidth product and 0.6 V/µs slew rate are the principal timing references, but the supplied data does not establish precision offset, low-noise performance, or calibration stability. Validate those specifications against the measurement accuracy and source impedance requirements before selecting it.

設計ノート
The verified MC3403D supply range is ±2.5 V to ±15 V, with a stated maximum supply voltage of 30 V. Design the regulator and decoupling network so normal supply tolerance, startup, and transients do not exceed the manufacturer’s absolute maximum. Place the required bypass capacitors close to the supply pins and use a low-impedance ground return; an amplifier that works on the bench can fail in production if supply noise or layout inductance is uncontrolled.
Use short, direct traces for non-inverting and inverting inputs, especially when the source impedance is high. Keep feedback components close to the relevant amplifier pins and route the output away from sensitive input nodes. The verified 1 MHz gain-bandwidth product and 0.6 V/µs slew rate do not guarantee stable operation at every gain, load, or supply condition; verify the intended noise gain and output load in the manufacturer datasheet before finalizing the feedback network.
Do not assume that a quad amplifier is a precision, rail-to-rail, or unity-gain-stable device without checking the specific datasheet. Verify input common-mode range, output swing, offset, bias current, noise, stability, and temperature limits for every amplifier channel. For replacements, confirm that the package pinout matches rather than relying on the device name, because the supplied results identify MC3403D listings from multiple manufacturers.
