Product Overview

MCP6002T-I/SN is a dual operational amplifier (Op Amp) in Microchip’s MCP6001/2/4 family, designed for low-power, general-purpose analog signal processing. It adopts an 8-Lead SOIC narrow-body package (SN package, 3.90mm×4.90mm) , integrating 2 independent Op Amps with a typical Gain Bandwidth Product (GBWP) of 1MHz per channel and a quiescent current (\(I_Q\)) of only 100μA per channel (VDD=5V). It supports a wide supply voltage range of 1.8~6.0V, operates over an industrial temperature range of -40~+85℃, and uses Tape and Reel packaging for SMT mass production.

As a dual Op Amp, the MCP6002T-I/SN features Rail-to-Rail input/output (I/O) with a common-mode input voltage range extended to \(V_{SS}-300mV\) to \(V_{DD}+300mV\), enabling full-scale signal processing in low-voltage systems. It delivers 90° typical phase margin (G=+1) for stable operation with 60pF capacitive loads, and offers low noise (28nV/√Hz input voltage density @1kHz) and high open-loop gain (88dB min.). Ideal for battery-powered devices, dual-sensor signal conditioning, active filters, and automotive auxiliary circuits, it balances integration, power efficiency, and stability for cost-sensitive applications.

Key Features

• Dual-Channel Integration for Space Savings：Integrates 2 independent Op Amps in one chip, reducing PCB area by over 40% compared to two single-channel Op Amps. Suitable for multi-channel signal processing (e.g., dual-temperature/pressure sensor amplification) in portable devices and instrumentation amplifiers.
  Ultra-Low Power for Extended Battery Life：100μA typical quiescent current per channel (VDD=5V), with a total current of ~200μA for dual-channel operation—67% lower than comparable dual Op Amps (e.g., TI TL072: 300μA per channel). No additional current in power-down mode, ideal for lithium-ion battery-powered devices (e.g., wireless sensor nodes, handheld medical tools).
  Wide Voltage Range + Rail-to-Rail I/O：1.8~6.0V supply voltage compatibility covers 3.7V lithium batteries, 5V industrial power, and 1.8V low-voltage MCU systems. Rail-to-Rail I/O eliminates signal clipping in low-voltage scenarios, with an output swing of \(V_{SS}+25mV\) to \(V_{DD}-25mV\) (VDD=5.5V, RL=10kΩ) for full-scale signal processing (e.g., ADC front-end conditioning).
  High Stability for Capacitive Loads：90° typical phase margin (G=+1) maintains 45° margin even with 500pF capacitive loads, avoiding gain peaking and oscillation. Output short-circuit protection (±6mA @1.8V, ±23mA @5.5V) prevents damage from overloads, suitable for capacitive load scenarios (e.g., LCD drives, filter capacitors).
  Industrial-Grade Reliability & Mass-Production Readiness：-40~+85℃ industrial temperature range tolerates harsh environments (e.g., automotive cabins, industrial control cabinets). The 8-Lead SOIC narrow package (3.90mm×4.90mm) saves space, and Tape and Reel packaging supports high-speed SMT placement, improving mass-production efficiency by 30%.
  Low Noise for Precision Signals：28nV/√Hz input voltage density (@1kHz) and 0.6fA/√Hz input current density (@1kHz) minimize distortion of weak signals (e.g., photodiode, strain gauge outputs), ideal for high-precision signal conditioning (e.g., medical physiological signal amplification).

Technical Specifications

Typical Applications

• Portable Electronics (Dual-Sensor Devices)：In smart bracelets and portable environmental monitors, it amplifies signals from both a temperature-humidity sensor (SHT30) and a pressure sensor (BMP280). Dual-channel integration reduces component count, and 100μA/channel low power extends battery life to over 1 month. Rail-to-Rail I/O ensures no signal clipping when transmitting small sensor signals (0~3.3V) to ADCs.
• Industrial Control (Instrumentation Amplifier Front-End)：In analog input modules for industrial PLCs, it serves as the input stage of instrumentation amplifiers, with dual channels processing the positive/negative ends of differential signals. 1MHz bandwidth supports 0~1kHz industrial signals (e.g., 4~20mA current loop to voltage conversion), and 88dB high open-loop gain improves signal linearity. The -40~+85℃ range adapts to factory temperature fluctuations.
• Automotive Electronics (Auxiliary Monitoring Circuits)：In automotive TPMS (Tire Pressure Monitoring Systems), it conditions signals from dual pressure sensors. The 1.8~6.0V wide voltage range tolerates fluctuations in the vehicle’s 12V-to-5V power supply. Output short-circuit protection prevents damage from automotive circuit overloads, and Tape and Reel packaging meets automotive mass-production requirements.
• Analog Filters (Dual-Channel Active Filters)：In audio equipment and data acquisition cards, it forms dual-channel 2nd-order Butterworth low-pass filters (100kHz cutoff frequency). 1MHz bandwidth ensures no filter performance degradation, 90° phase margin avoids oscillation, and low noise reduces audio signal distortion.
• Medical Devices (Dual Physiological Signal Amplification)：In portable heart rate monitors, it amplifies signals from both a PPG photodiode (heart rate) and a motion interference compensation sensor. 28nV/√Hz low noise minimizes interference in weak physiological signals, Rail-to-Rail I/O adapts to 3.7V lithium battery power, and industrial-grade temperature tolerance withstands post-sterilization temperature fluctuations.

Why Choose MCP6002T-I/SN ?

• Dual-Channel Integration + Small Package for Max Space Efficiency：Compared to two single-channel Op Amps (e.g., 2×MCP6001T-I/SN), the MCP6002T-I/SN reduces package footprint by 50%. The 8-Lead SOIC narrow package (3.90mm) fits miniaturized PCB designs, ideal for wearables and handheld devices.
• Low Power + Wide Voltage for Versatile Power Adaptation：100μA/channel quiescent current is 67% lower than comparable dual Op Amps (e.g., ADI AD8222: 300μA/channel). The 1.8~6.0V range eliminates the need for additional LDOs, simplifying systems powered by low-voltage MCUs or industrial 5V supplies.
• High Stability + Industrial-Grade Reliability：90° phase margin + output short-circuit protection ensures stable operation with complex loads (capacitive, inductive). -40~+85℃ industrial temperature range + 10000g shock resistance (0.2ms, unpowered) meets long-term reliability requirements in industrial and automotive environments.
• Low Noise + Rail-to-Rail for Precision Signals：28nV/√Hz low noise handles weak signals (e.g., nA-level photodiode current), while Rail-to-Rail I/O prevents signal clipping in low-voltage systems—ideal for medical and test equipment requiring high precision.
• Mass-Production Friendly + Comprehensive Ecosystem：Tape and Reel packaging supports high-speed SMT placement, improving yield. Microchip provides SPICE macro models, FilterLab® filter design software, Mindi™ circuit simulator, and application notes (e.g., AN884 for capacitive load driving), reducing development cycles by 30%.
