MCP662-E/SN - Dual 60MHz Rail-to-Rail Op Amp | Microchip
N.º de pieza: MCP662-E/SN ✓ ActivoMCP662-E/SN Descripción general
An operational amplifier is a voltage-controlled differential amplifier that uses feedback to amplify the difference between two input signals. The MCP662 belongs to the CMOS operational-amplifier hierarchy within analog and mixed-signal semiconductors. Its combination of high bandwidth, high output short-circuit current, and low-noise performance makes it suitable for filtering, buffering, sensor conditioning, audio signal paths, and communications equipment operating from a single low-voltage supply.
Key electrical features include a 79 dB typical common-mode rejection ratio, 6.8 nV/Hz typical input-voltage noise at 1 MHz, and a 90 mA typical output short-circuit current. The two-amplifier configuration allows one package to support simultaneous signal paths. Rail-to-rail output capability improves dynamic range when signals approach the positive or negative supply limits, while the 2.5 V minimum supply supports portable and embedded systems powered from regulated 3.3 V or lower rails.
The MCP66x family is optimized for high-speed operation. Its 60 MHz gain-bandwidth product allows operation at moderate closed-loop gains, and the 32 V/us slew rate supports rapid transitions in filtering, waveform generation, and data-conversion interface circuits. The 90 mA typical short-circuit current provides drive capability for capacitive loads and higher-impedance downstream stages, although external isolation may still be required for large capacitive loads.
Typical uses include low-voltage audio signal conditioning, ADC and DAC input or output buffering, active filters, portable instrumentation, industrial sensor interfaces, and communications equipment. The dual configuration can implement two independent amplifier channels or a differential signal-conditioning stage when the circuit requirements match.
Designers should verify stable operating-gain configurations, output-capacitance limits, input-bias behavior, and noise performance using the manufacturer datasheet. Place bypass capacitance close to the supply pins, provide adequate output-current margin, and use resistive isolation when driving large capacitive loads or long PCB traces.
This page combines the MCP662-E/SN electrical characteristics with same-package alternatives, application guidance, comparison parameters, and practical PCB design notes. It is intended to help engineers confirm footprint compatibility, speed, noise, supply range, and thermal requirements before integrating the amplifier into a new analog signal chain.

Aplicaciones típicas
MCP662-E/SN es adecuado para 6 aplicacións: Active Audio Filtering, ADC Input Signal Conditioning, Portable Sensor Conditioning, Low-Voltage Communications Interface, Instrumentation Buffering, Industrial Control Signal Interface.
Active Audio Filtering
The MCP662-E/SN fits dual-stage active filtering for low-voltage audio signals because its 60 MHz typical gain-bandwidth product provides bandwidth margin above the passband and its 32 V/us typical slew rate supports rapid signal transitions. The rail-to-rail output can improve utilization of a 2.5 V to 5.5 V supply when the filter waveform approaches either rail. Its 6.8 nV/Hz typical input-voltage noise at 1 MHz is also useful for reducing broadband contributions in buffered audio paths. Each amplifier channel can implement a separate filter section, allowing a balanced preamplifier or stereo crossover with a common package. The engineer should set resistor and capacitor values against the required gain, check stability, and keep source impedances within the manufacturer recommendations.
Recomendado
ADC Input Signal Conditioning
The MCP662-E/SN is appropriate for high-speed ADC input conditioning where a source must be buffered before conversion. Its 60 MHz typical gain-bandwidth product supports signal paths requiring substantially more bandwidth than many general-purpose precision amplifiers, while the 32 V/us typical slew rate reduces distortion during full-scale input transitions. The dual package can buffer two channels or provide gain and filtering functions in a differential front end. Rail-to-rail output operation is valuable when the ADC input range approaches the amplifier supply voltage. A practical design should use the converter's recommended source impedance and settling requirements, verify common-mode limits, and place the amplifier close enough to the ADC to minimize trace sensitivity.
Recomendado
Portable Sensor Conditioning
The MCP662-E/SN can condition outputs from sensors whose bandwidth rises above the range of low-power amplifier families. The 2.5 V minimum supply voltage supports compact 3.3 V systems, while the 0.0050 uA typical input bias current minimizes loading on high-impedance sensors. Its 60 MHz bandwidth and 32 V/us slew rate preserve fast transients from motion, optical, or industrial sensing elements, and the dual configuration can process complementary or redundant channels. Rail-to-rail output improves dynamic range when the conditioned signal must occupy much of the available supply range. Designers should account for sensor output capacitance, amplifier stability, input protection, and the higher current draw associated with a high-speed CMOS amplifier during battery-life analysis.

Low-Voltage Communications Interface
The MCP662-E/SN is useful for communications equipment requiring rapid analog signal transitions in a compact dual-op-amp package. Its 60 MHz typical gain-bandwidth product supports gain stages and impedance buffers operating well above audio frequencies, while the 32 V/us typical slew rate helps preserve waveform shape. The 90 mA typical output short-circuit current gives useful drive capability for downstream stages and capacitive loads encountered in communications modules. The rail-to-rail output allows a 2.5 V to 5.5 V design to maximize signal swing. Before layout release, check the maximum capacitive load, use series isolation where required, maintain short return paths, and confirm that adjacent switching circuitry does not overwhelm the amplifier's supply and input-noise performance.
Recomendado
Instrumentation Buffering
The MCP662-E/SN can provide fast differential and single-ended buffering in portable instrumentation. A typical differential arrangement uses one channel for the positive input and the other for the negative input, followed by a downstream subtraction stage or sampled by an ADC. The amplifier's 79 dB typical common-mode rejection ratio helps reject common-mode voltage, and its 60 MHz bandwidth handles transient instrumentation signals rather than only slow thermocouple or pressure signals. The 0.0050 uA typical input bias current reduces source-loading error with high-impedance sensors. Engineers should still evaluate resistor matching, input common-mode range, noise gain, output swing, and settling time. Precise layout and local supply bypassing remain important for preserving the benefit of the high-speed amplifier.
Recomendado
Industrial Control Signal Interface
The MCP662-E/SN fits industrial interface circuits that need faster edge rates than a general-purpose low-speed amplifier can provide. The dual-amplifier configuration can implement a gain stage and an active filter, or two independent line-driver channels. Its 60 MHz typical gain-bandwidth product and 32 V/us typical slew rate are useful when processing sensor signals, control-loop feedback, or actuator commands with modest transient content. Operation from 2.5 V to 5.5 V makes the device usable in distributed low-voltage control nodes. The -40 C to 125 C temperature range supports industrial environments. Design work should verify the actual output-current demand, maintain thermal margin, avoid excessive capacitive loading, and place supply-bypass components close to the package to limit supply ripple and transient coupling into the control signal.

Notas de diseño
Place the supply-bypass capacitor directly between the positive supply and ground pins, with the ground connection following the shortest practical return path. Keep sensitive input and feedback traces away from switching nodes and high-current outputs. Because the MCP662-E/SN has a 60 MHz typical gain-bandwidth product, board-level capacitance and long traces can materially affect high-frequency behavior. Use a continuous ground plane, minimize loop area around the device, and observe the manufacturer layout guidance.
Do not assume the 90 mA short-circuit-current rating is a continuous output-current rating. Check the datasheet output-current limits, output swing, temperature, and supply voltage for the intended load. Use a series isolation resistor when driving a capacitive input or long cable, and increase it as needed to maintain stability. Also verify that the selected closed-loop gain is stable for the specific feedback network rather than relying only on the nominal gain-bandwidth figure.
Calculate the operating power consumption from the supply voltage, quiescent current, output swing, and load current because the amplifier dissipates energy both internally and in the load. A 3.3 V design with one channel producing a 1 Vpp signal into 1 kohm dissipates approximately 3.3 mW in the load, while the amplifier adds its own internal and quiescent losses. Confirm junction-temperature margin at the highest ambient temperature and use exposed copper around the SOIC where the layout permits.
