MCP604-I/P 概述
A CMOS operational amplifier is a voltage-amplifying semiconductor in the amplifier IC hierarchy. It controls an output voltage according to the difference between two input voltages. Rail-to-rail output swing lets an amplifier approach its supply limits under suitable load conditions, while low supply voltage and low operating current suit portable, battery-powered, sensor, and instrumentation designs.
The MCP604 combines four amplifiers in one package, reducing board area compared with four separate single amplifiers. Its 2.8 MHz gain-bandwidth product supports general-purpose closed-loop signal amplification, while 230 uA typical operating current limits power demand in low-voltage systems. Advanced CMOS technology provides the device's low bias current, high speed, high open-loop gain, and output swing characteristics.
The family is specified for 2.7 V to 5.5 V supplies according to the manufacturer material supplied. Single-supply operation simplifies portable equipment, and the four-channel configuration suits sensor interfaces, active filters, voltage buffers, audio preamplification, and general instrumentation. The quad package also allows several circuit functions to be placed in one standardized footprint.
MCP604-E/P and MCP604-I/P appear in the supplied comparison sources and share the MCP604 identity and DIP-style option, but the suffix-specific temperature grade and every pin-level compatibility claim must be confirmed from the ordered-device datasheet before substitution. The PDIP package is through-hole rather than surface mount, so board footprint, pin spacing, and assembly method remain important.
This page consolidates the verified Microchip product description, distributor inventory references, package information, cross-reference findings, and engineering guidance. The primary design trade-off is integration: four amplifiers in one 14-pin PDIP package simplify quad-channel designs, but single or dual packages may offer a better fit when unused channels, board area, or power consumption matter.

典型应用
MCP604-I/P 适用于 6 应用s: Battery-Powered Sensor Signal Conditioning, Portable Instrumentation Front End, Active Audio Filtering, Low-Voltage Data Acquisition, Low-Voltage Buffering and Level Conditioning, Industrial Control Signal Conditioning.
Battery-Powered Sensor Signal Conditioning
The MCP604-I/P is suitable for multichannel sensor conditioning because it combines four CMOS amplifiers with a 2.7 V minimum single supply and a 230 uA typical operating current. Each channel can buffer a sensor output or amplify a small differential signal before conversion by an ADC. The low-voltage operation reduces the need for negative rails, while the quad package consolidates four amplifier functions. Confirm input bias current, common-mode range, noise, and settling behavior against the actual sensor and supply before release.
推荐
Portable Instrumentation Front End
For portable instrumentation, the MCP604-I/P provides four amplifiers for buffering, gain stages, and active filtering within a 2.7 V to 5.5 V supply environment. Its 2.8 MHz gain-bandwidth product gives useful bandwidth for general-purpose low-frequency and moderate-bandwidth measurements, while rail-to-rail output swing helps use the available supply range. Designers should verify input-referred noise, offset, and settling against the measurement bandwidth.
推荐
Active Audio Filtering
The quad MCP604-I/P can implement multiple active-filter sections in compact audio and communication equipment. Its 2.8 MHz gain-bandwidth product leaves bandwidth margin for moderate-frequency filter poles, and rail-to-rail output swing can improve utilization of a low-voltage audio supply. Because the MCP604 is a general-purpose CMOS amplifier, check output-current capability, output impedance, and distortion against the required load rather than assuming audio performance from bandwidth alone.
推荐
Low-Voltage Data Acquisition
MCP604-I/P is applicable when multiple analog channels must be amplified before an ADC or comparator in a low-voltage acquisition system. Four channels in one 14-pin PDIP package simplify board partitioning and can reduce the number of separate amplifier packages. The 2.7 V minimum supply is useful for compact embedded systems, but input range, offset, bias current, settling time, and ADC drive requirements must be evaluated for the selected gain and sampling rate.
推荐
Low-Voltage Buffering and Level Conditioning
The MCP604-I/P can buffer sensor, divider, or logic-interface signals when the design requires rail-to-rail output swing and low-voltage operation. Four independent channels allow a design to combine source followers, unity-gain buffers, and basic gain stages in one device. The 230 uA typical operating current is attractive for compact systems, though total current, input bias current, and capacitive-load stability remain important checks for high-impedance sources.
推荐
Industrial Control Signal Conditioning
MCP604-I/P can condition low-level control signals in industrial equipment when its verified supply and temperature ratings match the enclosure conditions. The quad configuration supports multiple feedback loops or conditioning channels while keeping the active device count low. The supplied data verifies the low-power CMOS architecture and 14-pin PDIP package, but an industrial selection must still check the ordered temperature grade, noise, offset, transient response, and compliance requirements for the specific application.

- Low-voltage operation （对比 MCP604-E/P)
- General-purpose speed and efficiency （对比 MCP604-I/SL)
设计说明
Budget the supply current for all four channels, not only the active load path. The verified typical operating current is 230 uA, but the final power estimate must also include input bias current, output current, external-divider current, and the actual supply voltage. Use local bypass capacitors at the supply pins and route returns to the quiet ground reference; exact capacitor values are [DATA_NEEDED: manufacturer-recommended decoupling values].
Keep the four amplifier inputs, feedback components, and supply connections compact and away from switching nodes or high-current return paths. A 14-pin PDIP package provides through-hole accessibility, but long input traces can increase noise pickup and sensitivity to parasitic capacitance. Check stability with the actual source resistance, load, gain, and cable length because the supplied data does not provide a complete stability-component recommendation.
Do not treat the MCP604-I/P suffix as interchangeable without comparing the ordered temperature and qualification rows. The supplied cross-reference results mention MCP604-E/P, MCP604-I/SL, MCP604T-I/SL, MCP604-E/STVAO, and MCP604-I/SN, but do not provide every suffix-specific rating. Confirm pinout, supply limits, gain-bandwidth product, bias current, output swing, and lifecycle status before approving a replacement.
合规信息
The supplied verified sources do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-mineral status for MCP604-I/P. AEC-Q100 is recorded as not_applicable only because no automotive qualification claim appears in the supplied target-specific data; this is not an automotive qualification statement.
