MCP6044-I/P - Quad 14 kHz Low-Power Op Amp | Microchip
部品番号: MCP6044-I/P ✓ 生産中MCP6044-I/P 概要
An operational amplifier is an active analog building block used to amplify voltage differences, buffer signals, perform comparisons, and implement analog signal-conditioning networks. The MCP6044 belongs to the CMOS operational-amplifier hierarchy and specifically targets portable and battery-powered equipment where low supply voltage, low quiescent current, and rail-to-rail signal swing are important. Four amplifiers are integrated into one package, reducing board area and simplifying multi-channel signal acquisition.
The MCP6044-I/P provides a 14 kHz gain-bandwidth product, typical operating current of 600 nA, input offset voltage below 3 mV, low bias current, high open-loop gain, and rail-to-rail output swing. These characteristics make the device useful for sensor interfaces, low-frequency filter stages, transducer amplifiers, portable measurement equipment, and general-purpose analog signal conditioning.
Microchip’s advanced CMOS technology is central to the device’s operation. The low-power bias circuitry and rail-to-rail input and output architecture allow the amplifier to operate near its supply rails, improving usable signal range in low-voltage systems. Because the gain-bandwidth product is 14 kHz, the device is intended for low-frequency and precision-oriented analog functions rather than high-speed signal processing.
Typical applications include battery-powered sensor interfaces, portable medical instrumentation, industrial process monitoring, environmental sensing, low-level signal amplification, and multi-channel data-acquisition boards. In each case, the quad configuration can support several amplifier channels while keeping the supply current and component count low.
When designing around the MCP6044-I/P, verify the exact input and output common-mode behavior, output-current capability, stability requirements, and recommended compensation network for the selected gain and load. The 14-pin PDIP package is also important for assembly planning because it differs from the SOIC and TSSOP versions of the MCP6044 family.
This page summarizes manufacturer and distributor information, pin-compatible alternatives, comparison parameters, and practical design guidance for engineers evaluating the MCP6044-I/P as a low-power quad op amp.

主な用途
MCP6044-I/P の用途: 6 件s: Battery-Powered Sensor Interfaces, Portable Medical Instrumentation, Industrial Process Monitoring, Low-Level Signal Conditioning, Environmental Monitoring, Data Acquisition Front Ends.
Battery-Powered Sensor Interfaces
The MCP6044-I/P fits low-voltage sensor front ends because each amplifier operates from a single supply as low as 1.4 V and consumes less than 1 µA maximum quiescent current per channel. Rail-to-rail input and output operation helps preserve signal range when sensor outputs move close to either supply rail. The quad package can provide four buffered or amplified channels for temperature, pressure, or environmental sensors without requiring four separate packages. Its 14 kHz gain-bandwidth product is suitable for low-frequency sensor signals rather than high-speed waveform conditioning.
おすすめ
Portable Medical Instrumentation
The MCP6044-I/P is appropriate for portable medical and diagnostic instrumentation requiring multiple low-power analog channels. Its 1.4 V minimum single-supply operation supports compact battery-powered designs, while the 600 nA typical operating current helps reduce the overall power budget. Four rail-to-rail amplifiers can buffer low-level physiological or diagnostic sensor signals in one 14-pin PDIP package. The 14 kHz bandwidth is suited to slow-moving analog measurements and instrumentation signals, with final medical qualification remaining the responsibility of the finished system.
おすすめ
Industrial Process Monitoring
The MCP6044-I/P can serve as the analog front end in industrial process-monitoring equipment that measures slowly changing sensor signals. Its low quiescent current reduces system overhead, and its rail-to-rail input/output behavior is useful when the process signal occupies much of the available supply range. The quad amplifier supports four channels for pressure, flow, level, or temperature monitoring while maintaining a compact through-hole footprint. The 14 kHz gain-bandwidth product fits slow process-control loops but not high-bandwidth sensor systems.
おすすめ
Low-Level Signal Conditioning
The MCP6044-I/P is well suited to low-level analog signal conditioning because its input offset voltage is specified below 3 mV and its CMOS architecture provides low bias current. The four integrated channels can be used for instrumentation-amplifier stages, transimpedance front ends, or active filtering around slow sensors. Rail-to-rail input and output operation improves signal utilization in low-voltage systems. Designers should confirm the exact offset and bias-current limits for the selected temperature condition before setting very high gain around the part.
おすすめ
Environmental Monitoring
The MCP6044-I/P can be used in environmental monitoring systems that combine several slow sensor channels with a low-power controller. Its 1.4 V minimum supply and less-than-1-µA maximum quiescent current per amplifier are advantageous in remote or battery-powered installations. Four channels can amplify and buffer signals from air-quality, humidity, temperature, or light sensors, while rail-to-rail operation accommodates signals near the supply limits. The package’s through-hole format also supports robust assembly in larger monitoring boards.
おすすめ
Data Acquisition Front Ends
The MCP6044-I/P fits multi-channel, low-frequency data-acquisition boards requiring four analog amplifier sections in one package. The 14 kHz gain-bandwidth product is adequate for buffered inputs, scaling stages, and anti-alias or smoothing networks operating at modest frequencies. Rail-to-rail input and output behavior supports single-supply operation, and the 600 nA typical current reduces overhead in distributed measurement nodes. For higher-bandwidth conversion systems, the analog signal path should be checked against the acquisition speed and required settling performance.

設計ノート
The MCP6044-I/P is specified for less than 1 µA maximum quiescent current per amplifier, with 600 nA typical operating current. Because four amplifiers are integrated, estimate the total quiescent demand by multiplying the per-amplifier figure by the number of continuously enabled channels and adding input, output-load, and leakage currents. Confirm that the selected supply regulator can support the complete load while maintaining the required voltage range.
Do not substitute SOIC-14 or TSSOP-14 MCP6044 variants for the MCP6044-I/P on an existing through-hole PCB. Those packages have different footprints and assembly requirements. If the temperature grade of MCP6044-E/P is used as a replacement, verify the full ordering-code and temperature-range requirements in the manufacturer datasheet rather than assuming that the headline 1.4 V, 14 kHz, and 600 nA ratings are the only differences.
Place the amplifier inputs, feedback components, and supply bypass capacitors close to the MCP6044-I/P pins to reduce parasitic impedance and sensitivity to noise. Keep sensitive input traces away from switching nodes and noisy return-current paths. Because the device is intended for low-frequency, low-noise operation, a quiet ground plane and short feedback routes are more valuable than unnecessary high-bandwidth layout techniques.
Use the 14 kHz gain-bandwidth product as the primary bandwidth constraint when selecting noise gain and closed-loop gain. Higher closed-loop gain reduces usable bandwidth and can increase sensitivity to output loading and stability. For filters or sensor amplifiers, calculate the expected closed-loop response and verify it against the capacitor and resistor tolerances used in the feedback network.
