MCP664-E/SL - Quad 60MHz RRO Op Amp | Microchip Technology
Teilenummer: MCP664-E/SL ✓ AktivMCP664-E/SL Übersicht
An operational amplifier, or op amp, is an analog integrated circuit that provides high open-loop gain and is commonly used to amplify, buffer, filter, compare, or drive signals within an electronic system. The MCP66x family from Microchip Technology is positioned for applications requiring high gain-bandwidth product and high output short-circuit current, with the MCP664-E/SL providing four amplifiers in one package.
Key specifications include a 60 MHz typical gain-bandwidth product, 32 V/µs typical slew rate, and 6.8 nV/√Hz typical input noise at 1 MHz. The device has four rail-to-rail output amplifier circuits in a 14-SOIC package. These characteristics make it suitable for audio processing, sensor signal conditioning, instrumentation, and other analog signal-chain designs where bandwidth and output drive are important.
The quad configuration allows four independent amplifier sections to be placed in one package, reducing board area compared with separate single op amps. Rail-to-rail output capability is useful when the signal must remain usable near the lower or upper end of the operating supply range. The 60 MHz bandwidth provides faster closed-loop response than low-frequency general-purpose amplifiers when configured with suitable feedback and compensation networks.
Typical uses include buffering sensor outputs, conditioning analog measurements, amplifying audio signals, driving ADC inputs, active filtering, and providing gain in instrumentation circuits. Designers should account for output-current limits, load capacitance, supply range, noise performance, and stability when selecting external feedback and decoupling components.
For PCB implementation, place the bypass capacitor close to the supply pins and route sensitive input and feedback connections away from high-current switching paths. Confirm the complete electrical limits, operating temperature range, and pin functions in the manufacturer datasheet before finalizing a production design.

Typische Anwendungen
MCP664-E/SL ist geeignet für 6 Anwendungs: Audio Signal Conditioning, Sensor Signal Conditioning, Precision Instrumentation, Active Filtering, Data Acquisition Front Ends, Industrial Control and Monitoring.
Audio Signal Conditioning
The MCP664-E/SL suits audio preamplifier and line-stage designs requiring four amplifier channels in one 14-SOIC package. Its 60 MHz typical gain-bandwidth product supports signals well beyond the audio band, while the 32 V/µs typical slew rate provides strong large-signal response. Rail-to-rail output operation is useful when the active signal must operate close to the available supply range. Each channel can implement gain, buffering, or active filtering when its offset, noise, and distortion characteristics meet the system requirement.
Empfohlen
Sensor Signal Conditioning
The MCP664-E/SL can amplify and buffer sensor outputs in instrumentation front ends where the required signal bandwidth exceeds that of a basic precision op amp. Four independent channels in the 14-SOIC package can reduce board area for multi-sensor systems. The 60 MHz typical gain-bandwidth product and 32 V/µs typical slew rate support responsive signal paths, but the input common-mode range and output swing must remain within the sensor's signal range. Add filtering close to the sensor to prevent unwanted high-frequency noise from reaching the amplifier.
Empfohlen
Precision Instrumentation
The MCP664-E/SL is appropriate for instrumentation stages that combine modest signal amplification with higher bandwidth than conventional low-noise amplifier families provide. Quad integration allows the same board to implement buffer, gain, difference, and active-filter functions. Its 6.8 nV/√Hz typical input noise at 1 MHz establishes a useful high-frequency noise figure, while rail-to-rail output operation can improve usable signal range. The complete bias, offset, drift, and common-mode characteristics should be reviewed against the measurement accuracy required by the instrument.
Empfohlen
Active Filtering
The MCP664-E/SL is useful in active-filter implementations requiring operational-amplifier bandwidth beyond ordinary low-frequency general-purpose parts. Its 60 MHz typical gain-bandwidth product allows closed-loop amplifier stages to operate at higher frequencies, and the 32 V/µs typical slew rate helps preserve large-signal behavior. The quad package can implement multiple filter sections in a compact area. Component tolerances, capacitor selection, noise gain, and the amplifier's stability with the chosen feedback network determine the practical filter response.
Empfohlen
Data Acquisition Front Ends
The MCP664-E/SL can drive and buffer inputs toward high-resolution data-conversion systems when signal bandwidth and output drive are priorities. Its four channels can support multiple analog channels or auxiliary conditioning functions in a 14-SOIC footprint, while rail-to-rail output operation helps maximize available signal range. Ensure that the selected ADC input range, sampling rate, settling requirements, and source impedance align with the amplifier's response. Place the amplifier and ADC input network so that switching and digital return currents do not disturb the analog node.
Empfohlen
Industrial Control and Monitoring
The MCP664-E/SL fits industrial monitoring circuits that condition low-level signals from sensors, transducers, or control interfaces. Quad integration supports several amplifier functions within one board area, while the high gain-bandwidth product supports faster feedback loops than low-frequency amplifier selections. Rail-to-rail output behavior can be beneficial in systems operating near a supply rail. Engineers should still verify noise immunity, supply range, common-mode limits, and temperature performance for the deployment environment before using the device in safety-critical control paths.

Designhinweise
Place the supply-bypass capacitor immediately adjacent to the MCP664-E/SL supply pins and provide a low-impedance ground return. With a 60 MHz typical gain-bandwidth product, long supply and ground paths can degrade performance or introduce instability. Route the four channels symmetrically where practical and keep high-current return currents away from sensitive input and feedback nodes.
Keep non-inverting inputs and inverting-feedback connections short, and avoid routing them parallel to digital clock, relay, or power-converter traces. Parasitic capacitance at the high-impedance input can alter gain and phase, particularly when the required closed-loop bandwidth approaches the amplifier's 60 MHz typical gain-bandwidth product. Confirm stability with the actual source impedance and load capacitance.
Calculate the required supply range from the output voltage, signal swing, input common-mode limits, and output-current demand. The MCP664-E/SL can deliver a 90 mA typical output short-circuit current, but sustained operation near that level requires careful attention to load, thermal conditions, and protection. Add the output-current budget for all four channels before assuming that every amplifier can drive its maximum load simultaneously.
Do not assume that rail-to-rail output operation guarantees the complete input common-mode range or exact output swing. Check both limits in the manufacturer datasheet against the signal being amplified, especially at 5 V or 3.3 V supply levels. Also avoid substituting a device solely because it uses a 14-SOIC package; verify amplifier-channel pin assignments, supply pins, control functions, and electrical limits.
