MCP662-E/MS - Dual 60 MHz Rail-to-Rail Op Amp | Microchip
Référence : MCP662-E/MS ✓ ActifMCP662-E/MS Présentation
An operational amplifier, or op amp, is an analog semiconductor that amplifies the voltage difference between its inverting and non-inverting inputs. A dual op amp contains two amplifier channels in one package, reducing board area and simplifying common supply and ground connections. Within the broader hierarchy, the MCP662-E/MS is a rail-to-rail amplifier, analog IC, and general-purpose signal-conditioning component.
The 60 MHz gain-bandwidth product makes the MCP662-E/MS suitable for higher-frequency feedback networks, including video, communications, instrumentation, and active filtering. Rail-to-rail output operation improves output-voltage range utilization, while the dual-channel configuration supports complementary signal paths or two independent channels. The -E suffix identifies an extended-temperature product, while /MS denotes the 8-pin MSOP packaging used by the MCP662 family.
Microchip describes the MCP66x family as featuring high gain-bandwidth product and high output short-circuit current. Those characteristics support low-impedance drive of downstream circuitry and operation in feedback systems where closed-loop bandwidth is more important than static offset or noise alone. Because op-amp performance depends on supply voltage, output loading, feedback topology, and external components, practical bandwidth should be evaluated in the final circuit rather than inferred solely from the gain-bandwidth figure.
Typical uses include active filters, sensor-conditioning stages, communications interfaces, video signal chains, audio buffers, and general instrumentation. The two channels may drive successive filter stages, process complementary signals, or implement a small closed-loop amplifier when appropriate feedback resistors are selected. Its MSOP package also supports compact designs where analog performance and routing density are both important.
When laying out the circuit, place input and feedback components close to the amplifier pins to minimize parasitic capacitance and feedback-loop area. Keep sensitive input nodes away from high-current output paths, provide adequate supply bypassing, and verify stability with realistic source impedance, load capacitance, and output-drive requirements before committing the layout.

Applications typiques
MCP662-E/MS convient pour 6 applications: Active Signal Filtering, Instrumentation Signal Conditioning, Communications Interface Conditioning, Video Signal Buffering, Sensor Front-End Buffering, Industrial Data Acquisition.
Active Signal Filtering
The MCP662-E/MS is suitable for active filter implementations because its dual configuration places two amplifier stages in one 8-pin MSOP package, while the 60 MHz gain-bandwidth product provides bandwidth for moderate- and high-frequency response shaping. The two channels can implement successive low-pass, high-pass, band-pass, or notch stages, reducing board area compared with separate single-channel amplifiers. Rail-to-rail output can also improve usable signal swing in filter stages. Component values must be selected for the target gain and frequency, and each stage should be checked for noise gain, phase margin, source impedance, and load stability. The manufacturer electrical tables should define the permissible operating region for the final filter topology.
Recommandé
Instrumentation Signal Conditioning
For instrumentation front ends, the MCP662-E/MS can provide two closely related low-level signal-conditioning stages, such as a non-inverting preamplifier followed by a gain or filter stage. Its 60 MHz gain-bandwidth product supports feedback networks that require appreciable closed-loop bandwidth, and the dual package reduces routing distance between amplifier sections. Rail-to-rail output provides flexibility in signal-chain headroom, although input offset and bias current remain important error sources for precision measurements. The design should account for sensor-source impedance, sensor grounding, resistor-network tolerances, and the amplifier's common-mode behavior. Review the exact MCP662 datasheet for offset, bias current, noise, and stability limits before setting the gain.
Recommandé
Communications Interface Conditioning
The MCP662-E/MS can condition communication-interface signals when the required bandwidth falls within the amplifier's 60 MHz gain-bandwidth capability. A dual arrangement can amplify and filter one signal, or process two related channels such as a signal and its complement. Rail-to-rail output helps maximize dynamic range when supply headroom is limited, while the extended-temperature grade may suit industrial equipment. Practical implementation still requires control of impedance, ringing, and channel-to-channel layout. Place terminations and feedback networks according to the interface specification, minimize trace lengths, and verify the amplifier against the source amplitude, data rate, duty cycle, and required jitter. Supply and ground return paths must remain low impedance to prevent modulation of the communication signal.
Recommandé
Video Signal Buffering
The MCP662-E/MS is applicable to video buffering and termination tasks where a 60 MHz gain-bandwidth product and rail-to-rail output align with common low-to-moderate video-bandwidth requirements. The two channels can buffer separate video lines or form gain and filtering stages in a video chain. Input and output impedance, gain flatness, slew rate, and output-current capability determine how closely the device follows a particular video standard. Source termination and cable or board losses should be represented during evaluation, and unused amplifier inputs must be connected so they do not amplify noise. Confirm the amplifier's settling behavior and capacitive-drive stability in the manufacturer documentation before using it in precision timing or high-resolution imaging paths.
Recommandé
Sensor Front-End Buffering
The MCP662-E/MS can buffer high-impedance sensor outputs when the design requires two amplifier channels and bandwidth beyond that of a general-purpose low-frequency op amp. Rail-to-rail input and output terminology should be verified for the exact device because the listed data explicitly confirms rail-to-rail output but does not state the input common-mode range. The two channels may buffer two sensors or amplify and filter one sensor. Leakage from PCB contamination, input bias current, capacitance, and thermal gradients can dominate a high-impedance design, so use guarding, clean routing, and appropriate feedback values. Confirm the sensor's output range and the MCP662 input-common-mode limits in the manufacturer documentation before selecting the device for a precision or low-current sensor interface.
Recommandé
Industrial Data Acquisition
The MCP662-E/MS is well suited to compact industrial data-acquisition blocks that need two general-purpose amplifiers for analog conditioning. It can amplify sensor outputs, implement anti-alias filtering, or buffer inputs before an external converter. The dual 8-pin MSOP construction reduces board area, and the 60 MHz gain-bandwidth product provides margin for many moderate-bandwidth acquisition chains. The -E temperature designation is relevant to equipment exposed to wider environmental conditions, but the exact limits must be checked against the system's enclosure temperature. Designers should include input protection, stable feedback components, local supply bypassing, and grounding that separates analog signals from switching converters and digital return currents.

Principaux différenciateurs

- Rail-to-rail output in an 8-pin MSOP (vs MCP661-I/MS)
Notes de conception
Place input, feedback, and compensation components directly beside the MCP662-E/MS pins. Keep the high-impedance input traces short, enclose them with a grounded guard where appropriate, and avoid routing them parallel to output or switching-current paths. Connect the bypass return to the quiet ground plane rather than through the analog input reference network. These layout measures reduce parasitic feedback and coupling that can alter filter response or cause instability.
Evaluate closed-loop behavior with the intended noise gain rather than treating 60 MHz as the usable signal bandwidth. Include source impedance, load capacitance, output-current demand, and external compensation in the analysis. If the source is capacitive or the feedback loop is long, use the compensation method specified by the manufacturer. Confirm settling and distortion for the signal bandwidth because gain-bandwidth product alone does not specify pulse accuracy or phase margin.
Do not leave an unused amplifier channel floating. If only one MCP662 channel is used, connect the unused input to a stable common-mode voltage within its rated range and configure the unused output as an appropriate follower. Also check whether the circuit actually requires rail-to-rail input operation; the distributor description explicitly identifies rail-to-rail output, while the input common-mode range requires confirmation in the manufacturer datasheet.
Use the lowest supply voltage that satisfies signal swing, common-mode, and output-drive requirements, because supply headroom affects internal operating margin. Decouple the supply at the IC with a short, low-inductance connection and provide adequate energy-storage capacitance for transient loads. Verify output-current capability for the selected gain because the MCP66x family's high output short-circuit current is a capability indicator, not an unlimited continuous-load specification.
Informations de conformité
The distributor listing describes MCP662-E/MS as automotive-rated, but exact AEC-Q100 qualification and environmental compliance declarations require confirmation from Microchip.
