MCP604-I/SL - 2.8MHz Quad CMOS Op Amp | Microchip
N.º da peça: MCP604-I/SL ✓ AtivoMCP604-I/SL Visão geral
An operational amplifier is an analog signal-conditioning semiconductor that amplifies the difference between two input voltages. The MCP604 belongs to the CMOS operational-amplifier hierarchy, combining low power consumption with rail-to-rail output capability. Four amplifiers are integrated into one package, allowing compact implementations of filters, buffers, transducers, and general-purpose analog signal chains.
The MCP604 family uses Microchip advanced CMOS technology, providing low bias current, high open-loop gain, and rail-to-rail output swing. Its 2.8 MHz gain-bandwidth product supports moderate-frequency closed-loop operation, while the 230 uA typical operating current is useful in battery-operated and low-power equipment. The verified comparison data also identifies a maximum input offset voltage of 2,000 uV and a minimum supply voltage of 2.7 V.
With four amplifier channels in one 14-pin SOIC, the MCP604 can reduce the number of packages needed for multi-channel analog designs. Rail-to-rail output swing is useful when the usable output range is close to the supply rails, particularly in low-voltage systems. The maximum 6.0 V supply voltage supports compatibility with conventional 3.3 V and 5 V circuit rails when operating conditions permit.
Typical uses include low-frequency sensor conditioning, active filtering, audio preamplification, battery-powered instrumentation, ADC or DAC input and output buffering, and four-channel process-control interfaces. The low typical operating current and single-supply operation make the device practical for portable measurement systems and industrial equipment sharing a 2.7 V to 6.0 V supply domain.
Designers should verify the complete manufacturer electrical characteristics for the configured gain, load, supply voltage, and temperature. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs must be connected to a defined potential. Because no verified pin-level description was supplied, this page does not infer individual pin functions.
This page combines verified manufacturer specifications, distributor availability and pricing, same-family replacement information, application guidance, and comparison parameters. It also identifies missing pinout, compliance, and detailed operating data rather than presenting unverified electrical values as guaranteed specifications.

Aplicações típicas
MCP604-I/SL é adequado para 6 aplicaçãos: Battery-Powered Sensor Conditioning, Industrial Process Measurement, Portable Audio Preamplification, Active Filtering and Signal Conditioning, ADC and DAC Interface Buffering, Low-Voltage Control and Instrumentation.
Battery-Powered Sensor Conditioning
The MCP604-I/SL fits low-power sensor signal conditioning because it operates from 2.7 V to 6.0 V and has a 230 uA typical operating current. Four channels in one 14-pin SOIC can amplify weak sensor outputs, buffer reference nodes, or implement active filtering without requiring four separate packages. Its 2.8 MHz gain-bandwidth product is suitable for many low-frequency resistance, temperature, and pressure sensors, while rail-to-rail output swing helps preserve usable dynamic range in compact battery-powered instruments. The design must still verify sensor excitation current, output loading, input bias requirements, and noise at the required signal bandwidth.
Recomendado
Industrial Process Measurement
The MCP604-I/SL is suitable for industrial process-measurement interfaces that operate from a 2.7 V to 6.0 V control rail and require four analog channels. Its industrial temperature range of -40C to +85C supports equipment deployed in controlled factory environments, while the quad configuration can support current-to-voltage conversion, buffering, gain stages, and active filters. The 2.8 MHz bandwidth is adequate for many process signals below 100 kHz, depending on closed-loop gain and stability requirements. Designers should verify the sensor output common-mode range and isolation from high-voltage industrial wiring.
Recomendado
Portable Audio Preamplification
The MCP604-I/SL can serve as a low-power preamplifier in portable audio and communication equipment because its 230 uA typical operating current supports battery-operated operation. Four rail-to-rail-output channels allow the device to handle multiple low-level signal stages, while the 2.8 MHz gain-bandwidth product exceeds the bandwidth of many conventional audio paths. The amplifier can be used for microphone or line-level conditioning where its maximum input offset voltage of 2,000 uV is acceptable. For high-fidelity audio, engineers should also verify noise density, input bias current, output-load capability, and channel-to-channel behavior against the complete manufacturer data.
Recomendado
Active Filtering and Signal Conditioning
The MCP604-I/SL is appropriate for small-signal active filters and conditioning blocks because its 2.8 MHz gain-bandwidth product provides useful closed-loop bandwidth for many low-to-moderate-frequency networks. Four amplifiers in a 14-pin SOIC allow multiple poles, gain stages, or buffers to be implemented compactly. Operation from a single 2.7 V to 6.0 V supply simplifies portable and embedded analog systems, while rail-to-rail output supports signals near the supply limits. Component tolerances and amplifier stability should be checked for each filter topology, especially at high gain or with capacitive loading.
Recomendado
ADC and DAC Interface Buffering
The MCP604-I/SL can buffer ADC inputs, DAC outputs, and intermediate analog nodes in low-voltage embedded systems. Its rail-to-rail output swing allows the output to approach the available signal range more closely than a fixed-headroom amplifier, while 230 uA typical operating current limits power use in portable equipment. Four channels are useful for gain adjustment, reference buffering, or driving successive-conversion systems. The device’s maximum offset of 2,000 uV, closed-loop bandwidth, capacitive drive, settling behavior, and ADC input requirements must be compared with the converter’s accuracy and sampling architecture.
Recomendado
Low-Voltage Control and Instrumentation
The MCP604-I/SL supports compact control and instrumentation systems that operate on a 2.7 V to 6.0 V supply and need several general-purpose analog amplifier channels. Typical uses include error amplifiers, analog summing stages, actuator-driver preamplifiers, and signal isolator interfaces. Its -40C to +85C industrial temperature range broadens deployment beyond consumer equipment, while the 2.8 MHz gain-bandwidth product handles many control-loop and instrumentation signals. Designers must account for output-current limits, capacitive loads, input common-mode range, and stability when driving downstream stages.

Notas de projeto
The MCP604 family has a verified typical operating current of 230 uA, but production designs should not treat that value as a maximum across temperature and output load. Place the device supply-decoupling capacitor close to the supply pins and connect the ground pins to a low-impedance return path. When estimating battery life, include amplifier quiescent current, sensor excitation, load current, regulator quiescent current, and the operating duty cycle.
No verified pin-function table was supplied, so do not infer connections from generic quad-op-amp layouts. Obtain the current Microchip MCP604 family datasheet or CAD model and follow its package drawing before routing traces. Keep sensitive input nodes short, separate output routing from high-impedance inputs, and provide a direct ground reference to reduce parasitic feedback and common-mode coupling.
MCP604-E/SL, MCP604T-I/SL, and MCP604T-E/SL are not automatically interchangeable with MCP604-I/SL merely because they use the same 14-pin SOIC. Confirm the temperature grade, rail-to-rail-output description, input offset requirements, supply limits, and shutdown behavior in the manufacturer ordering table. Also ensure every unused amplifier input is tied to a defined potential rather than left floating.
The 2.8 MHz gain-bandwidth product is a closed-loop bandwidth guide rather than a guaranteed usable frequency at every gain. Check the required noise gain, phase margin, output capacitive load, and channel stability against the complete manufacturer characteristics. For sensor signals near the supply rails, evaluate input common-mode range, rail-to-rail output behavior, offset error, and whether the required precision justifies the 2,000 uV maximum input offset.
