MCP6004-I/P - Quad 1MHz Low-Power Op Amp | Microchip
Teilenummer: MCP6004-I/P ✓ AktivMCP6004-I/P Übersicht
An operational amplifier, or op amp, is a high-gain analog signal-processing component that compares two input voltages and amplifies the difference between them. Within the power-management and signal-conditioning hierarchy, the MCP6004 belongs to the general-purpose amplifier class, combining four independent amplifier channels in one integrated circuit. Rail-to-rail input and output capability lets each channel operate close to the supply rails, which is useful in low-voltage systems where the available signal range is limited.
Key features include four amplifier channels, a 1.8 V minimum operating supply, a 6 V maximum operating supply, 1 MHz typical gain-bandwidth product, and 100 µA typical quiescent current. The MCP6004-I/P also provides rail-to-rail input and output behavior. These characteristics make it suitable for low-power sensor conditioning, buffering, general analog signal processing, and mixed-signal systems that require multiple amplifier functions without using four separate packages.
The 1 MHz gain-bandwidth product supports operation from low-frequency signal conditioning through moderate-bandwidth applications. At unity gain, the usable bandwidth is approximately 1 MHz under typical conditions. Rail-to-rail input capability supports sensing signals near the positive or negative supply limit, while rail-to-rail output allows the amplifier to produce output voltages close to either rail. Actual output swing and stability still depend on load, supply voltage, frequency, and the surrounding circuit.
Typical uses include sensor signal conditioning, low-frequency active filtering, voltage buffering, transimpedance stages, instrumentation interfaces, and general-purpose analog gain stages. The four integrated channels can also implement functions such as dual differential amplifiers, comparators with suitable feedback arrangements, or multiple single-ended amplifier stages. Because the MCP6004-I/P operates from 1.8 V to 6 V, it is especially relevant to portable, embedded, industrial-control, and low-voltage instrumentation designs.
Designers should verify the required output-current capability, operating temperature grade, noise, offset voltage, and stability under the intended load before finalizing the circuit. Decoupling capacitors should be placed close to the supply pins, and sensitive analog inputs should be kept away from fast-switching nodes. The 14-lead PDIP package also requires adequate spacing between adjacent board-level circuits because its through-hole leads are larger than those of surface-mount packages.
This product record combines verified manufacturer and distributor information, exact package identification, purchasing data, application guidance, and an honest review of available drop-in alternatives. It also highlights where additional verification is needed, including the complete pin mapping and alternative qualification, rather than presenting unsupported assumptions as confirmed specifications.

Typische Anwendungen
MCP6004-I/P ist geeignet für 6 Anwendungs: Low-Voltage Sensor Signal Conditioning, Portable Instrument Front End, Industrial Analog Control Interface, Active Audio and Communication Buffering, Voltage Buffering and Level Conditioning, Low-Frequency Active Filtering.
Low-Voltage Sensor Signal Conditioning
The MCP6004-I/P fits sensor-conditioning paths that operate from a 1.8 V to 6 V supply and require amplification close to the available signal range. Its rail-to-rail input is useful when a sensor output moves near either supply rail, while the typical 1 MHz gain-bandwidth product supports moderate-frequency conditioning. Four channels allow gain, filtering, and buffering stages to share one package. The designer should verify the sensor output impedance and required noise performance, then confirm that the selected gain does not reduce stability or usable bandwidth.
Empfohlen
Portable Instrument Front End
The MCP6004-I/P is appropriate for portable measurement equipment where four analog channels are needed at low supply voltage. Its 100 µA typical quiescent current per amplifier helps limit standby consumption, and its 1.8 V minimum operating voltage supports compact battery-powered systems. The four channels can provide input buffers, gain stages, or active-filter sections. Because the PDIP package is relatively large, a surface-mount implementation may be preferable for a highly miniaturized product, and the total four-channel quiescent demand must be included in battery sizing.
Empfohlen
Industrial Analog Control Interface
The MCP6004-I/P can support low-voltage industrial interface circuitry when its specified operating-temperature grade is suitable for the environment. Rail-to-rail input and output operation accommodates control signals that occupy much of a 1.8 V to 6 V supply range, and the four channels reduce the number of packages needed for actuator and sensor interfaces. Designers should add appropriate filtering, verify isolation boundaries, and ensure that the amplifier does not replace the protection, grounding, and surge-handling measures required by the final industrial system.
Empfohlen
Active Audio and Communication Buffering
The MCP6004-I/P can buffer low-level signals in audio and communication equipment operating from a low-voltage supply. Its 1 MHz typical gain-bandwidth product is sufficient for many baseband buffering and general gain applications, while four channels provide flexibility for input, output, and intermediate stages. Rail-to-rail output can maximize signal range in compact systems. Audio or RF-adjacent designs should nevertheless check noise, slew rate, output loading, channel-to-channel behavior, and the actual signal bandwidth from the manufacturer datasheet.
Empfohlen
Voltage Buffering and Level Conditioning
The MCP6004-I/P is well suited to unity-gain voltage buffering because its rail-to-rail output provides useful swing at low supply voltages. Multiple buffered outputs can distribute a reference or conditioned control voltage without loading the source stage. The typical 1 MHz bandwidth gives ample margin for many low-frequency buffer networks, but source impedance, capacitive loading, and stability must be considered. Engineers should use the four available channels only when their combined quiescent current and output load remain within the power-budget and thermal targets of the design.
Empfohlen
Low-Frequency Active Filtering
The MCP6004-I/P can implement first-order and modest second-order active-filter sections where the 1 MHz typical gain-bandwidth product provides useful bandwidth beyond the intended signal band. Rail-to-rail input and output are valuable in low-voltage systems because they preserve a larger fraction of the available signal range. Four channels allow a multi-section filter to be realized in one package. Component tolerances, amplifier gain error, output loading, and the actual phase margin must be evaluated, particularly for higher-order filters or signals approaching the amplifier's useful bandwidth.

Wichtigste Unterscheidungsmerkmale
- Industrial-grade suffix distinguishes the selected temperature option (vs. MCP6004-E/P)
- Four general-purpose amplifiers in one 14-lead PDIP package (vs. MCP6004-E/P)
- Low-voltage operation with full-range signal access (vs. MCP6004-E/P)
Designhinweise
Budget the power supply for four channels rather than one. With a typical quiescent current of 100 µA per amplifier, the four amplifiers contribute approximately 400 µA before output-current demand is added. This is an estimate using the manufacturer’s typical per-amplifier value; actual consumption depends on supply voltage, output swing, load, frequency, and channel activity. Decoupling capacitors should be placed close to the supply pins.
Do not treat package compatibility as sufficient for unqualified substitution. The MCP6004-E/P uses the same 14-lead PDIP configuration, but its -E temperature-grade designation differs from the -I grade of MCP6004-I/P. Before replacement, compare the manufacturer datasheet limits for temperature, input offset voltage, common-mode rejection, output swing, and supply current. The verified results do not quantify every grade-level difference.
Place bypass capacitors close to the device supply pins and keep sensitive input traces away from switching nodes and high-current return paths. The MCP6004-I/P can operate down to 1.8 V, where layout-induced noise and supply ripple can occupy a meaningful portion of the signal range. Use a quiet ground reference, minimize loop area, and verify stability with the actual source impedance, load, and feedback network.
Check the closed-loop gain against the typical 1 MHz gain-bandwidth product before selecting the feedback network. Higher closed-loop gains reduce bandwidth, while capacitive loading can impair stability in otherwise conventional voltage-feedback amplifiers. Use the manufacturer application guidance and SPICE simulation where available, particularly for sensor interfaces with long leads or source impedances above the recommended range.
Compliance-Informationen
The supplied verified snippets do not provide unambiguous compliance declarations for the MCP6004-I/P. An Arrow listing contains automotive and AEC-Q100 terms, but the snippet does not establish that the exact -I/P suffix is AEC-Q100 qualified, so no qualification claim is made.
