MCP6002-E/P - Dual 1MHz Low-Power Op Amp | Microchip
MPN： MCP6002-E/P ✓ 啟用中MCP6002-E/P 概覽
An operational amplifier, or op amp, is an analog signal-conditioning IC that uses high open-loop gain to amplify differences between two input voltages. The MCP6002 belongs to the operational-amplifier hierarchy and is specifically intended for general-purpose voltage amplification, buffering, filtering, and low-frequency signal-processing circuits where low power consumption and rail-to-rail signal handling are valuable.
The amplifier's rail-to-rail input stage accepts input voltages across most of the supply range, while its rail-to-rail output stage can approach the positive and negative supply rails under suitable load conditions. This makes the MCP6002 useful in battery-powered equipment, sensor interfaces, and mixed-signal systems operating from 1.8 V to 6 V. Its 1 MHz typical gain-bandwidth product supports modest closed-loop bandwidth requirements rather than high-speed signal processing.
Microchip specifies a typical quiescent current of 100 µA and a typical 90° phase margin for the MCP6001, MCP6002, and MCP6004 family. Low quiescent current reduces the standing load imposed by each active channel, which is especially helpful in two-channel designs where both amplifiers may operate continuously. The dual configuration also reduces package count and can simplify board layout compared with two separate single amplifiers.
Typical applications include low-frequency sensor conditioning, audio preamplification, voltage buffering, active filtering, joystick or potentiometer interfaces, and portable instrumentation. The 8-lead PDIP package is particularly useful for prototypes, educational equipment, through-hole industrial assemblies, and designs where a socket or hand-soldering is preferred over a fine-pitch surface-mount footprint.
Designers should account for input common-mode behavior, output swing, noise, stability with the selected feedback network, and the limits of a 1 MHz amplifier when planning closed-loop gain. Decoupling capacitors should be placed close to the supply pins, and unused inputs should be biased into a valid common-mode range. The DIP outline also requires adequate clearance for through-hole drilling and component spacing.
This page combines the manufacturer's device characteristics, documented package choices, equivalent-amplifier guidance, and practical selection criteria. It is intended to help engineers determine whether the MCP6002-E/P's low-power dual-channel architecture and PDIP package fit a specific analog circuit without confusing it with faster, noisier, or more highly integrated alternatives.

典型應用
MCP6002-E/P 適用於 6 應用s: Battery-Powered Sensor Conditioning, Audio Preamplification, Active Filters and Signal Conditioning, Portable Instrumentation, Potentiometer and Joystick Interfaces, Industrial Control and Data Acquisition.
Battery-Powered Sensor Conditioning
The MCP6002-E/P suits low-power sensor interfaces because it operates from 1.8 V to 6 V, supports rail-to-rail input and output, and draws 100 µA typical quiescent current. Place one channel in a non-inverting or differential conditioning stage and use the second channel for reference buffering or active filtering. The 1 MHz typical gain-bandwidth product comfortably supports many temperature, pressure, and light-sensor signals with kilohertz-level bandwidth. Its advantage is simple, low-power dual-channel integration; the trade-off is that it is not intended for high-speed sensor signals requiring much greater closed-loop bandwidth or lower input noise.
推薦
Audio Preamplification
The MCP6002-E/P can implement two low-frequency audio preamplifier channels in a single 8-lead PDIP. Rail-to-rail output allows the amplifier to use more of the available signal swing, while the 1 MHz typical gain-bandwidth product is suitable for many line-level and low-frequency instrument stages. A typical implementation would use non-inverting gain around one channel and an inverting summing or active-filter stage in the other. Check input-referred noise, output drive, and load impedance against the signal level, and keep the closed-loop bandwidth well below the amplifier's 1 MHz gain-bandwidth product.
推薦
Active Filters and Signal Conditioning
The dual MCP6002-E/P is well matched to first- and second-order active-filter implementations that operate at low or moderate frequencies. Its 1 MHz typical gain-bandwidth product leaves useful bandwidth headroom for passive-component tolerances and closed-loop gain, while 100 µA typical quiescent current supports compact instrumentation. The two independent channels can implement a cascaded filter, oscillator, or separate signal-conditioning paths without requiring two packages. Component selection must include amplifier stability, maximum output swing, and the effect of loading on the selected filter topology.
推薦
Portable Instrumentation
The MCP6002-E/P fits portable measurement equipment that needs two analog channels without the power cost of higher-bandwidth amplifiers. Its 1.8 V minimum operating voltage supports low-voltage systems, and rail-to-rail input and output reduce signal-range restrictions near the rails. One channel can amplify a sensor output while the other buffers a reference or drives an anti-alias filter. Designers should budget the 100 µA typical quiescent current for both channels and account for sensor excitation, ADC input current, and display or processing loads when evaluating battery life.
推薦
Potentiometer and Joystick Interfaces
The MCP6002-E/P can buffer resistive position sensors whose wiper voltage may approach either supply rail. Rail-to-rail input and output behavior helps preserve signal range in low-voltage control systems, and the dual amplifier can handle two axes or provide a second buffer for reference conditioning. A typical circuit connects the potentiometer between the supply rails and the wiper to a non-inverting amplifier input, with a modest feedback network setting the gain. Avoid excessive capacitive loading on the output, keep the source impedance within the amplifier's recommended range, and verify stability when driving long cables or ADC inputs.
推薦
Industrial Control and Data Acquisition
The MCP6002-E/P is appropriate for low-frequency industrial control modules that require dual analog channels, modest bandwidth, and a through-hole package for maintainable assemblies. It can condition a control-voltage input and buffer a feedback node, or amplify two sensor outputs into an ADC front end. The 1.8 V to 6 V supply range supports compact embedded systems, while the PDIP outline simplifies prototype revision and socket-based maintenance. Industrial qualification requirements such as AEC-Q100, extended-temperature operation, and particular safety standards must be verified separately before deployment in regulated equipment.

設計說明
Do not assume that matching package outlines guarantees identical amplifier behavior. Before replacing MCP6002-E/P with TLV9002IP, TLV9062IP, or OPA2392IP, compare the complete manufacturer pin descriptions, maximum supply voltage, input bias current, output swing, offset voltage, noise, slew rate, and stability requirements. In particular, the MCP6002 supports operation up to 6 V, while the replacement guidance describes a 5.5 V limit for the TI candidates. Preserve the DIP outline and pin orientation, but validate the electrical substitution.
Place the supply bypass capacitor directly between the positive and negative supply pins, with the shortest practical ground path. The 8-lead PDIP package provides ample spacing for through-hole assembly, but the op-amp pins should still be kept away from high-current switching nodes and high-impedance input traces. Orient the DIP according to its notch and pin-1 marking, maintain adequate lead bending clearance, and check that neighboring components do not block access to the socket or pins during maintenance.
Use a feedback topology that keeps the closed-loop bandwidth comfortably below the 1 MHz typical gain-bandwidth product, especially when driving capacitive loads. Keep sensor source impedances low enough for the amplifier's bias-current and noise contribution to remain acceptable. Bias any unused channel into a valid common-mode range rather than allowing it to float above or below the supply rails. For filtering stages, calculate resistor and capacitor tolerances because component variation can move the actual bandwidth or closed-loop gain.
Estimated: using a 3.3 V supply at 100 µA typical quiescent current for both amplifier channels, the nominal internal device supply consumption is approximately 0.33 mW. This excludes load current, input-bias effects, leakage, and external circuitry. The estimate demonstrates why the amplifier is attractive for portable systems, but it should not be treated as a complete power budget or as a substitute for the manufacturer's worst-case electrical characteristics.
