MC3403PG - Quad 1 MHz Operational Amplifier | onsemi
Référence : MC3403PG ✓ ActifMC3403PG Présentation
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.

Applications typiques
MC3403PG convient pour 6 applications: Industrial Sensor Conditioning, Low-Frequency Active Filters, Audio Preamplification, Transducer Signal Interfaces, Legacy Control-System Amplifiers, Test and Measurement Front Ends.
Industrial Sensor Conditioning
The MC3403PG fits four-channel industrial sensor conditioning because each amplifier provides true differential inputs, a 1 MHz gain-bandwidth product, and a 0.6 V/us slew rate within one 14-DIP package. Place the quad device between sensor outputs and a higher-level analog or digital acquisition stage, using separate feedback networks for each channel. The 3 V to 36 V single-supply range supports common industrial rails, while the -25C to +85C rating covers ordinary controlled environments. Verify input-common-mode limits and output swing at the actual supply voltage because the MC3403PG is a general-purpose amplifier.
Recommandé
Low-Frequency Active Filters
The MC3403PG is suitable for building low-frequency active filters because its four channels provide a 1 MHz gain-bandwidth product and 0.6 V/us slew rate. Engineers can use one package for cascaded low-pass, high-pass, or notch stages, reducing component count and simplifying through-hole assembly. The 3 V to 36 V single-supply operation permits direct interface with industrial signal levels, but each filter must be checked for component tolerance, closed-loop gain, and stability. Source impedance and capacitive loading should remain within the limits defined by the manufacturer datasheet.
Recommandé
Audio Preamplification
The MC3403PG can support four audio preamplifier channels in equipment requiring a 1 MHz gain-bandwidth product and true differential inputs. Its 0.6 V/us slew rate is appropriate for many low-to-mid-frequency audio stages, while the quad package reduces board space compared with four separate single amplifiers. A 3 V to 36 V supply range supports portable and fixed installations, but audio designers should verify output headroom, gain-bandwidth margin, and input-noise performance in the operating band. Keep feedback loops short and maintain adequate return paths between amplifier stages.
Recommandé
Transducer Signal Interfaces
The MC3403PG is useful for transducer interfaces that require differential sensing and four available amplifier channels in a through-hole package. Its 10 mV maximum input-offset rating and 1 MHz gain-bandwidth product support low-frequency pressure, position, and resistance-bridge conditioning, provided common-mode and output-swing requirements are satisfied. The single 3 V to 36 V supply reduces system complexity when sensors operate from a positive rail. Use a reference-ground strategy appropriate to the sensor and confirm that input bias-current effects do not disturb the bridge or source impedance.
Recommandé
Legacy Control-System Amplifiers
The MC3403PG suits legacy industrial control boards because it combines four operational amplifiers, a single 3 V to 36 V supply range, and a serviceable 14-DIP package. It can implement error amplifiers, current-to-voltage converters, comparators with positive feedback, and general feedback-control functions in one IC. The -25C to +85C commercial range and 1 MHz bandwidth suit ordinary control-loop bandwidths, but supply-current, output-current, and saturation behavior should be checked at the actual load. Socketed construction can also simplify field replacement.
Recommandé
Test and Measurement Front Ends
The MC3403PG can form the input stage of a general-purpose test or measurement instrument using one amplifier for buffering and the remaining channels for gain, offset, or filtering functions. Its true differential inputs are useful when the source must reject common-mode noise, and its 1 MHz gain-bandwidth product covers many low-frequency instrumentation tasks. The 14-DIP package is convenient for educational and legacy through-hole instruments. For precision measurements, evaluate input bias current, offset drift, and noise in addition to the 10 mV maximum input-offset specification before calibrating the system.

Notes de conception
Place the supply bypass capacitor as close as practical to the 14-DIP supply pins, with a short ground return to avoid adding inductance to the amplifier's supply loop. Keep each input and feedback component close to its associated channel, especially for active-filter circuits. Route high-impedance input nodes away from switching-node copper and transformers to reduce coupled noise that could obscure the 1 MHz small-signal bandwidth.
Do not assume that a 36 V operating ceiling permits every amplifier function at 36 V. Check the required input common-mode range, output swing, output-current capability, and power dissipation at the actual supply voltage. The 10 mV maximum input-offset rating also means that precision measurements may require calibration or a more accurate amplifier. Confirm stability with the final feedback network, source impedance, and load capacitance.
For a dual in-line package, preserve socket clearance and keep the board edge or adjacent components from obstructing pin 1 orientation. If replacing the device in legacy equipment, verify the socket's pin numbering and the manufacturer's pin-description table before inserting a substitute. This prevents rotation errors and incorrect assignment of the shared V+ and V- supply connections across four amplifier channels.
Supply-voltage headroom must account for the complete input and output signal swing; a nominal 36 V rail does not establish that the output can swing to the rail. Decouple the device locally and calculate total package current plus load current against the power-source capability. The MC3403PG's general-purpose architecture supports low-frequency feedback loops, but it should not be used as a power-output stage without checking output-current and thermal limits.
