MC3303D - Quad 30V 1MHz Op Amp | Texas Instruments
MPN: MC3303D ✓ פעילMC3303D סקירה
An operational amplifier is a voltage-feedback amplifier used to amplify, buffer, filter, compare, or reshape analog signals. Quad operational amplifiers combine four amplifier channels in one package, reducing board area and simplifying designs that need multiple analog functions. The MC3303D belongs to the broader hierarchy of operational amplifier, analog amplifier, analog IC, and semiconductor.
Key verified features include four amplifier circuits, single-ended circuit configuration, a 30 V supply rating for the Texas Instruments MC3303D, and a unity-gain bandwidth of 1 MHz. The onsemi MC3303D listing additionally describes a voltage-feedback architecture, 0.6 V/µs slew rate, nominal 14 V supply, and an operating-temperature range from -40 °C to 85 °C. Because MC3303D is used by more than one manufacturer, engineers should confirm the manufacturer-specific orderable datasheet before release.
The MC3303D combines four high-voltage-capable amplifiers in a 14-terminal SOIC-14 package. Its approximately 1 MHz bandwidth is suitable for general-purpose signal processing, including audio-frequency stages, control loops, sensor interfaces, and active filtering. The available verified data does not state input offset voltage, input bias current, noise density, common-mode input range, output swing, or short-circuit current for the Texas Instruments version.
Typical uses include four-channel sensor conditioning, low-frequency active filters, instrumentation stages, audio preamplification, comparator-style threshold circuits, and general analog buffers. Because four independent channels are integrated, a design can also use the amplifiers for mixed functions such as gain, filtering, level shifting, and output buffering without using four separate packages.
Designers should verify input common-mode range, output swing, input offset, bias current, noise, stability, and compensation requirements against the exact manufacturer datasheet. The verified web results identify different electrical details for the Texas Instruments, onsemi, and STMicroelectronics versions sharing the MC3303D suffix, so package compatibility alone does not prove specification compatibility.
This page combines verified manufacturer and distributor information with practical procurement guidance, explicitly identifies unavailable electrical parameters, and distinguishes same-package drop-in candidates from broader functional equivalents. It is intended to support engineering selection without treating devices with identical suffixes from different manufacturers as automatically interchangeable.

יישומים טיפוסיים
MC3303D מתאים עבור 6 יישוםs: Industrial Sensor Conditioning, Audio Preamplification, Active Filtering, Process Control Loops, Battery-Powered Monitoring, Test and Measurement Buffering.
Industrial Sensor Conditioning
The Texas Instruments MC3303D is suitable for general-purpose sensor conditioning when the design uses a 30 V maximum supply and signals below its approximately 1 MHz unity-gain bandwidth. Four integrated amplifiers can support sensing, amplification, filtering, and output buffering without requiring four separate packages. For industrial instrumentation, however, the exact manufacturer datasheet must be checked for input offset voltage, input bias current, common-mode range, output swing, noise, and channel matching because those values were not present in the verified data. A practical arrangement is a sensor followed by a non-inverting gain stage, an active low-pass filter, and a unity-gain buffer, with the fourth channel reserved for monitoring or reference conditioning.
מומלץ
Audio Preamplification
MC3303D can support low-frequency audio preamplification because the verified Texas Instruments product information specifies approximately 1 MHz unity-gain bandwidth and four amplifier channels in a compact SOIC-14 package. The four channels may process stereo audio or support additional filtering and monitoring stages, although the exact input-noise and output-drive specifications were not supplied. Designers should use the manufacturer-specific data sheet to verify input offset, bias current, common-mode range, output swing, and stable operation at the intended gain. The onsemi listing for the identically suffixed device reports a 0.6 V/µs slew rate, but that value must not automatically be attributed to the Texas Instruments version.
מומלץ
Active Filtering
The four channels in MC3303D provide a practical basis for cascaded active filters and signal-conditioning networks. Its approximately 1 MHz unity-gain bandwidth offers useful margin for low-frequency crossover, smoothing, and noise-shaping stages, but the achievable response remains dependent on the exact open-loop response and stability data in the selected manufacturer's datasheet. Component tolerances and the amplifier's input-offset behavior can materially influence low-frequency accuracy. Use the verified 30 V Texas Instruments supply rating to establish the rail budget, then verify common-mode input range and output swing before selecting resistor and capacitor values. Stable operation near unity gain and acceptable phase margin must also be confirmed from the applicable documentation.
מומלץ
Process Control Loops
MC3303D is applicable to low-frequency industrial control loops when four channels can perform sensing, error amplification, filtering, and actuator-signal buffering. The verified 30 V supply rating can accommodate industrial signal-chain requirements, while the approximately 1 MHz bandwidth is generally well above the bandwidth of many slow process-control loops. It does not replace a dedicated instrumentation amplifier when high common-mode rejection is required, because no instrumentation-amplifier rating was supplied for this device. Verify input bias current, offset voltage, common-mode range, output swing, slew rate, and supply-current behavior against the purchased manufacturer's data sheet before closing a control loop.
מומלץ
Battery-Powered Monitoring
MC3303D can be used in portable or battery-powered monitoring electronics when four low-frequency analog channels justify a single multi-amplifier package. The compact 14-pin SOIC format helps conserve board area, and the approximately 1 MHz bandwidth is suitable for many sensor and thresholding functions rather than high-speed waveform processing. Because the verified results do not provide quiescent current, shutdown behavior, or input-noise density for the Texas Instruments device, battery-life calculations cannot rely on those figures until the manufacturer data sheet is reviewed. Verify the minimum operating voltage, rail-to-rail input and output limits, load capability, and leakage-related specifications, particularly if the source impedance is high or the signal approaches the supply rails.
מומלץ
Test and Measurement Buffering
The four independent channels of MC3303D can serve as general-purpose buffers and amplifiers around low-frequency test fixtures. The approximately 1 MHz unity-gain bandwidth is adequate for many general-purpose measurement paths, while the 30 V Texas Instruments supply rating provides a higher nominal operating ceiling than typical low-voltage mixed-signal rails. Nevertheless, the verified information does not establish input bias current, output impedance, capacitive-load stability, settling time, or common-mode input range. Use the exact manufacturer datasheet to determine whether the amplifier can directly drive the selected ADC, resistor network, or probe. Buffer sensitive sources close to the measurement device and confirm rail-to-rail behavior where required.

הערות תכנון
Confirm the manufacturer before schematic release because Texas Instruments, STMicroelectronics, and onsemi all use the MC3303D suffix. Although the verified listings generally identify a 14-pin SOIC format, manufacturer-specific supply ratings, offsets, bias currents, common-mode limits, output swing, and pin details may differ. Record the manufacturer and complete ordering code in the BOM, and compare the purchased part against the schematic symbol and footprint rather than relying on the suffix alone.
Place input and output paths for each channel away from switching-node and high-current return paths to reduce coupled noise. Keep the amplifier ground connection short and provide a stable ground reference close to the device. Because the verified information does not include input capacitance, output impedance, or capacitive-load stability limits, avoid driving long cables or large capacitive loads until stability is confirmed from the exact manufacturer datasheet and the complete application circuit.
Design the supply rail below the applicable manufacturer-specific maximum, which is 30 V for the Texas Instruments MC3303D listing. The onsemi listing for the same suffix states operation up to 36 V, but that higher value must not be used for a Texas Instruments part. Decouple the supply pins according to the selected datasheet and calculate amplifier dissipation from the actual rail voltage, output voltage, load current, and number of active channels. No quiescent-current or output-current values were supplied, so those calculations remain incomplete.
The approximately 1 MHz unity-gain bandwidth limits the useful small-signal bandwidth, while stability and large-signal behavior depend on the exact topology and load. Verify phase margin, gain-bandwidth behavior, output swing, and slew rate for the selected manufacturer before constructing filters with high Q or attempting to drive low-impedance loads. For low-frequency precision measurements, include input-offset and bias-current error in the uncertainty budget and choose resistor values that minimize interaction with input bias current.
