MCP655-E/MF - Dual 50MHz R-R Op Amp | Microchip Technology
Артикул: MCP655-E/MF ✓ АктивенMCP655-E/MF Обзор
An operational amplifier is a high-gain analog signal-conditioning IC used to amplify, buffer, compare, and filter voltages. The MCP655-E/MF belongs to the MCP65x family of rail-to-rail amplifiers with mCal calibration. Within the product hierarchy, it is an operational amplifier, analog amplifier, and signal-conditioning IC used in electronic control, measurement, and interface systems.
The two amplifiers provide 50 MHz gain-bandwidth product and 30 V/us slew rate, allowing the devices to process higher-frequency signals than general-purpose low-speed amplifiers. Rail-to-rail input and output operation improves dynamic range in low-voltage systems where the useful signal can approach either supply rail. The manufacturer identifies a typical low offset of 200 uV and a supply current of 6 mA for this amplifier family.
The MCP65x devices use mCal to self-calibrate at power-up, reducing initial offset error without requiring a separate trimming procedure. Package options with a calibration or chip-select function can also support low-power operation and scheduled offset calibration. The exposed thermal pad provides a low-impedance path for heat removal, but its effectiveness depends on the PCB thermal design and the copper area connected to the pad.
Typical uses include sensor signal conditioning, current measurement, active filtering, audio and communication interfaces, and low-voltage embedded control. The MCP655-E/MF is particularly suitable for compact designs that require two high-speed amplifiers and rail-to-rail signal handling without the larger footprint of a traditional dual SOIC.
When laying out the circuit, place input and output decoupling capacitors close to their associated supply pins and connect the exposed pad to a ground plane with thermal vias. Confirm input and output common-mode limits, output-current capability, and capacitive-load stability against the manufacturer datasheet for the selected operating conditions.
This product page combines manufacturer-level operating details, package information, application guidance, comparison parameters, and practical layout notes to support faster component selection and PCB implementation.

Типичное применение
MCP655-E/MF подходит для 6 применениеs: Low-Voltage Sensor Signal Conditioning, Current Measurement and Instrumentation, Active Audio and Communication Filtering, Data Acquisition and ADC Drivers, Industrial Control and Automation, Portable and Battery-Powered Electronics.
Low-Voltage Sensor Signal Conditioning
The MCP655-E/MF fits sensor front ends that operate from a 2.5 V to 5.5 V rail and need useful signal range close to the supply limits. Its rail-to-rail input and output stages support amplification of sensor outputs without selecting a higher-voltage amplifier, while the 50 MHz gain-bandwidth product gives ample bandwidth for filtering and settling. Use one channel for level shifting or buffering and the other for gain or active filtering, then verify common-mode limits against the sensor output.
Рекомендуется
Current Measurement and Instrumentation
The MCP655-E/MF can amplify the small differential voltage produced by current-sense resistors in precision measurement systems. Its 200 uV typical input offset and 50 MHz gain-bandwidth product help preserve low-level measurement integrity, while dual-channel operation supports simultaneous sensing, buffering, or active filtering. Check input bias current, common-mode range, and shunt voltage at the maximum current before finalizing the gain and protection network.
Рекомендуется
Active Audio and Communication Filtering
The MCP655-E/MF is suitable for active filters and communication-signal conditioning because its 50 MHz gain-bandwidth product and 30 V/us slew rate provide more bandwidth than typical low-speed dual amplifiers. The rail-to-rail output can improve utilization of a 2.5 V to 5.5 V supply, while mCal reduces power-up offset. Account for amplifier noise, layout-induced oscillation, and the attenuation requirements of the intended filter when setting component values.
Рекомендуется
Data Acquisition and ADC Drivers
The dual MCP655-E/MF can provide low-impedance drive to an ADC input or support two channels of analog conditioning before conversion. A 50 MHz gain-bandwidth product is appropriate for many moderate-speed acquisition systems, and rail-to-rail operation helps preserve signal amplitude at low supply voltages. Confirm the ADC settling requirements, input capacitance, and sampling rate, then place the amplifier output close enough to the converter to minimize capacitive loading and signal degradation.
Рекомендуется
Industrial Control and Automation
The MCP655-E/MF fits compact industrial control boards requiring two rail-to-rail amplifiers for transducer interfaces, error amplifiers, and actuator feedback loops. Operation down to 2.5 V supports low-voltage sensor and control systems, while the exposed-pad DFN package preserves board area. Industrial designs should still check temperature grade, supply-noise tolerance, EMC requirements, and output-current limits, and should isolate the analog ground path from high-current switching returns.
Рекомендуется
Portable and Battery-Powered Electronics
The MCP655-E/MF can support compact battery-powered equipment where a dual amplifier saves board area and rail-to-rail operation improves low-voltage signal utilization. The family specification identifies 6 mA supply current, while mCal performs power-up self-calibration to reduce offset. Select external resistance and capacitance values carefully to minimize power use, confirm the amplifier's quiescent-current behavior across the full supply range, and account for longer system startup if calibration affects initialization timing.

Заметки по проектированию
Place the input, output, and supply-connection components close to the DFN leads. Connect the exposed pad to a quiet ground plane with several thermal vias, and keep high-current return paths away from the input and feedback nodes. Because rail-to-rail input stages can respond to parasitic coupling differently from conventional bipolar inputs, keep clock, motor-drive, and switching-regulator nodes away from the signal path.
The exposed pad is the principal thermal path for the 10-DFN package. Use as much uninterrupted ground copper as practical and distribute multiple vias around or beneath the pad. Estimate dissipation from output-current demand and supply voltage, then verify the resulting junction temperature using the PCB thermal model and the package limits in the manufacturer datasheet. An EP-connected footprint without thermal vias may perform much worse than the package rating alone suggests.
Do not assume every 10-pin DFN dual op amp is interchangeable because lead assignments, exposed-pad connections, and calibration pins can differ. Confirm pin 1, the supply pins, input and output assignments, and the exposed pad using the MCP655-E/MF pin-description table. Also check the output-swing limits at the selected supply voltage and load before using the rail-to-rail designation as a guarantee of full output swing.
For high-gain or high-frequency operation, use short feedback traces and place compensation or filtering capacitors directly at the relevant pins. Avoid routing inputs and outputs in parallel unless their coupling is intentional. The 50 MHz gain-bandwidth product provides considerable bandwidth, but stability still depends on output loading, gain, feedback topology, and the PCB return path, so validate the assembled design with appropriate test equipment.
