MCP604-E/P Visão geral
An operational amplifier, or op amp, is a high-gain differential amplifier used to amplify, buffer, filter, or compare analog signals. The MCP604 belongs to the CMOS operational-amplifier family and is designed for low-power, single-supply systems. Four amplifiers in one package reduce board area and simplify designs requiring multiple gain stages or independent analog channels. The 2.7 V to 5.5 V operating range supports 3 V and 5 V systems, while rail-to-rail output swing improves usable output range near the supply rails.
The 2.8 MHz gain-bandwidth product provides useful bandwidth for low-frequency precision, audio, sensor, and general signal-conditioning circuits. The typical operating current of 230 uA per amplifier is appropriate for battery-powered and portable equipment. Low bias current helps preserve source impedance, while high open-loop gain supports accurate closed-loop amplification. The MCP604-E/P is identified as a CMOS amplifier with four circuits and rail-to-rail operation in the verified distributor data.
The MCP604-E/P uses Microchip advanced CMOS technology to combine low power, low bias current, and rail-to-rail output performance. Its general-purpose architecture supports non-inverting, inverting, summing, comparator-style, and active-filter implementations when operated within the datasheet limits. Designers should account for input common-mode range, output swing, noise, stability, and load limitations when selecting external compensation or filter components.
Typical uses include portable sensor interfaces, low-voltage audio signal chains, transducer amplification, current-to-voltage conversion, active filters, and general instrumentation. Because each package contains four amplifiers, it is especially suitable for multi-channel designs where board space and power consumption are important. The quad arrangement can also implement differential stages, sample-and-hold-related buffers, and multiple feedback control loops.
For PCB layout, keep input and output paths short, provide stable supply bypassing close to the device, and avoid routing sensitive high-impedance inputs beside noisy switching nodes. The PDIP package is suitable for through-hole assembly and prototyping, while the -E/P order suffix denotes the supplied temperature-range and package variant according to the manufacturer naming system. Confirm the exact electrical limits and pin mapping against the Microchip MCP604 datasheet before production use.
This page consolidates verified manufacturer and distributor information for the MCP604-E/P, identifies the practical trade-offs of its 14-pin PDIP package, and provides comparison and design guidance for engineers evaluating quad low-power CMOS operational amplifiers. Pricing, availability, and lifecycle information should be checked against live distributor inventory before committing a production order.

Aplicações típicas
MCP604-E/P é adequado para 6 aplicaçãos: Portable Sensor Signal Conditioning, Low-Voltage Audio Buffering, Active Filtering and Control Loops, Precision Current-to-Voltage Conversion, General-Purpose Instrumentation Buffering, Data Acquisition Front End.
Portable Sensor Signal Conditioning
The MCP604-E/P fits portable sensor interfaces because four low-power amplifiers can condition multiple channels from a common 2.7 V to 5.5 V supply. Its 230 uA typical operating current per amplifier helps limit battery drain, while low bias current supports higher-impedance sources that would otherwise be loaded by the input network. Rail-to-rail output swing increases the usable range for sensor-derived signals on low-voltage rails. Designers can use each amplifier for a non-inverting front end, active filter, or level-shift stage. The principal limitation is the 2.8 MHz gain-bandwidth product, which is better suited to low-frequency and moderate-bandwidth sensing than demanding wideband instrumentation.
Recomendado
Low-Voltage Audio Buffering
The MCP604-E/P is useful in low-voltage audio boards where rail-to-rail output swing and compact quad integration matter. Four amplifiers can implement buffered summing stages, channel gain controls, headphone-driver support circuits, or active crossover sections around a 2.7 V to 5.5 V supply. The 2.8 MHz gain-bandwidth product covers many speech, control, and line-level audio functions, although it is not a high-bandwidth audio-power solution. Rail-to-rail output behavior helps preserve signal amplitude near either supply rail, and the 230 uA typical operating current supports power-conscious portable designs. Output loading, slew rate, and stability should still be checked for the selected gain and source impedance.
Recomendado
Active Filtering and Control Loops
The MCP604-E/P supports active-filter and feedback-loop designs in industrial control, instrumentation, and educational equipment. Four independent amplifiers provide flexibility for cascaded low-pass sections, transimpedance stages, error amplifiers, and PI-control loops without requiring four separate packages. Its 2.8 MHz gain-bandwidth product permits moderate closed-loop bandwidth, while low bias current helps preserve high-impedance sensor nodes. The 2.7 V to 5.5 V range accommodates common 3.3 V and 5 V rails. Component tolerances and amplifier noise determine the achievable filter accuracy, so verify those datasheet limits and include appropriate supply bypassing when setting component values and stability margins.
Recomendado
Precision Current-to-Voltage Conversion
The MCP604-E/P can form a transimpedance amplifier for photodiode, sensor, or electrochemical measurement circuits when the required signal bandwidth is moderate. The low bias current of the advanced CMOS MCP604 family helps preserve the integrity of high-source-impedance feedback networks, and four amplifiers allow a transimpedance stage, buffer, gain stage, and output driver to share one 14-pin PDIP package. Rail-to-rail output swing improves utilization of a 2.7 V to 5.5 V supply. The 2.8 MHz gain-bandwidth product and 2.3 V/us slew rate set the practical upper limits, particularly with feedback capacitance. PCB leakage, guard rings, and stray capacitance can matter more than nominal amplifier accuracy in high-impedance designs.
Recomendado
General-Purpose Instrumentation Buffering
The MCP604-E/P is appropriate for laboratory and industrial instrumentation that needs several buffered analog channels on a low-voltage board. The quad package reduces component count and simplifies power distribution compared with four discrete single amplifiers. Its 2.8 MHz gain-bandwidth product supports general-purpose gain and buffering at low-to-moderate frequencies, and rail-to-rail output improves measurement utilization on 3.3 V or 5 V rails. The 230 uA typical operating current per channel is advantageous in distributed measurement systems. For precision instrumentation, engineers should verify input offset voltage, input voltage noise, input bias-current variation, common-mode range, and open-loop gain from the complete manufacturer datasheet because those numerical limits are absent from the supplied excerpts.
Recomendado
Data Acquisition Front End
The MCP604-E/P can form the analog front end of a low-speed data-acquisition board by conditioning sensor outputs before an ADC. Four amplifiers provide channel buffering, differential-to-single-ended conversion, programmable-gain support, or active anti-alias filtering in a single 14-pin PDIP. The 2.7 V to 5.5 V operating range allows it to share either 3.3 V or 5 V analog rails, while 230 uA typical operating current per amplifier supports compact multi-channel systems. The 2.8 MHz gain-bandwidth product is generally sufficient for many moderate-rate sensors but must be compared with ADC acquisition bandwidth and settling requirements. Decouple the analog supply locally and keep high-impedance sensor routes away from digital switching paths.

Notas de projeto
Place the MCP604-E/P close to the signals it buffers and keep each feedback loop compact. High-impedance inputs should be short, guarded where appropriate, and kept away from clocks, switching regulators, and relay traces. Because the MCP604 uses a 14-pin PDIP with exposed through-hole leads, check lead spacing and mechanical clearance during PCB layout. The DIP package also increases board height, which can matter in compact enclosures.
The verified data identifies a 2.7 V to 5.5 V supply range and 230 uA typical operating current per amplifier. Confirm that every rail remains within those limits during startup and transient conditions, and avoid treating the typical current as a maximum. Four amplifiers can represent approximately 920 uA under the stated typical per-amplifier condition before considering additional chip current and board-level loads. Use the manufacturer datasheet for the final maximum-current and supply-decoupling requirements.
The 2.8 MHz gain-bandwidth product and 2.3 V/us slew rate limit how quickly the MCP604-E/P can follow larger signals. Avoid operating it as a wideband video or RF amplifier, and verify closed-loop stability for each gain configuration, especially with capacitive loads. For active filters, account for amplifier noise and finite gain-bandwidth when calculating response and settling. Keep input and output loops separated to reduce the risk of oscillation.
Rail-to-rail output does not guarantee that the input common-mode range covers both supply rails, and it does not remove the need to check output loading. Do not infer exact offset, noise, common-mode, or temperature limits from the distributor summaries. Review the official MCP604 datasheet for those parameters and confirm the package pin mapping before wiring. Also distinguish MCP604-E/P from similar suffixes such as -I/P and -SL variants before procurement.
