MCP6072T-E/SN 개요
An operational amplifier (op amp) is a high-gain DC-coupled electronic voltage amplifier with differential inputs and a single-ended output, used as a fundamental building block in analog signal chains. Rail-to-rail input/output (RRIO) op amps can accept input signals at or near both supply rails and swing their outputs to within millivolts of either rail, which maximizes dynamic range in low-voltage single-supply systems. The MCP6072 belongs to the voltage-feedback amplifier family, sits in the linear IC hierarchy (op amp -> amplifier IC -> integrated circuit -> semiconductor), and is widely used as a precision, low-power alternative to general-purpose op amps.
Key features of the MCP6072 include unity-gain stability (no compensation capacitor required), operation from a single supply as low as 1.8 V up to 6.0 V, 110 µA typical quiescent current per channel, ±150 µV maximum input offset voltage, and 1.2 MHz typical gain bandwidth product. The 8-pin SOIC (SN) package supports surface-mount assembly with standard 1.27 mm pitch and reflow-solderable lead finish.
The internal architecture uses a CMOS input stage with rail-to-rail input common-mode range and a complementary output stage for rail-to-rail output swing. The low offset voltage, low bias current, and wide supply range make the device well suited to sensor-interface and battery-powered applications where both precision and low power are required.
Typical applications include battery-powered instrumentation, transducer amplification, signal conditioning for sensor outputs, analog filtering, and portable medical or industrial devices. The MCP6072 is also used as a precision buffer for ADC drivers and as a building block in active filter implementations.
When designing with the MCP6072, ensure the input common-mode voltage stays within the rails and account for the 0.5 V/µs slew rate when selecting feedback components for higher-frequency signals. Decouple the supply pin with a 0.1 µF ceramic capacitor placed close to the device for stable operation.

Battery-Powered Sensor Signal Conditioning
The MCP6072T-E/SN's 110 µA typical quiescent current per channel and 1.8 V minimum supply operation make it an excellent fit for battery-powered sensor signal conditioning. With ±150 µV maximum input offset voltage and rail-to-rail input/output swing, it accurately amplifies low-level bridge, thermocouple, or photodiode signals near the supply rails where general-purpose op amps fail. The 1.2 MHz GBW supports gain configurations up to 10x on signals up to 100 kHz, and the SOIC-8 package sits in a compact 3.9 mm footprint. Powered by two AA cells (3 V), each amplifier burns only ~330 µW, extending battery life in wireless sensor nodes. Place a 0.1 µF ceramic decoupling capacitor close to the V+ pin and route the input traces as differential pairs to maximize CMRR.

Transducer and Bridge Amplifier
For strain-gauge bridges, load cells, and pressure transducers, the MCP6072T-E/SN's low offset voltage (±150 µV max) and rail-to-rail output swing directly improve measurement accuracy in single-supply 3.3 V or 5 V systems. The 1.2 MHz GBW and 0.5 V/µs slew rate comfortably handle the modest bandwidth requirements of industrial transducer loops (typically <10 kHz). The dual op amp enables a classic instrumentation configuration (two MCP6072 channels plus external gain resistors) at a fraction of the cost of dedicated INA families. Use 0.1% matched resistor pairs and a low-pass filter on the output to limit noise; the 110 µA/ch Iq keeps standby dissipation under 1 mW per channel.
추천
ADC Driver / Precision Buffer
The MCP6072T-E/SN is well matched as a precision buffer or driver for successive-approximation ADCs operating from 3.3 V or 5 V rails. Its rail-to-rail input stage accepts signals that swing to within millivolts of either supply rail, and the output stage drives the ADC's switched-capacitor input without distortion thanks to its unity-gain stability and 0.5 V/µs slew rate. The low input offset voltage preserves ADC accuracy, while 110 µA quiescent current per channel is negligible compared to typical ADC active currents. Place a 0.1 µF ceramic between the op amp output and the ADC input as a charge reservoir for the ADC's sampling transients, and add an anti-alias RC network ahead of the amplifier.
추천
Active Filter and Signal Processing
The MCP6072T-E/SN enables implementation of Sallen-Key, multiple-feedback (MFB), and state-variable active filters for frequencies up to about 100 kHz. Its 1.2 MHz GBW places the practical upper limit around the 100-200 kHz range before phase margin erodes. The rail-to-rail output allows filter signals to swing close to the supply rails, maximizing dynamic range. The dual amplifier enables a 2-pole Sallen-Key low-pass or band-pass filter using only one IC. Choose resistor values to keep impedance above 10 kΩ to avoid loading the op amp output stage, and bias the non-inverting input at mid-rail for maximum symmetrical swing.
추천
Portable Medical and Wearable Devices
The MCP6072T-E/SN's low quiescent current (110 µA/ch), extended -40°C to +125°C operating range, and small SOIC-8 footprint suit portable medical and wearable devices such as pulse oximeters, ECG signal chains, and body-worn monitors. Its rail-to-rail input stage accepts biophysical signals that swing near either supply rail, while the low offset voltage preserves amplitude accuracy in single-supply designs. The dual op amp implements a complete two-channel biopotential front end (one channel for the signal, one for the right-leg drive or reference). Power from a single Li-ion cell (3.6-4.2 V) to keep dissipation under 1 mW total, and apply proper ESD and EMI guarding for medical safety.
추천
Industrial 4-20 mA Loop Conditioning
For 4-20 mA current-loop transmitters and receivers, the MCP6072T-E/SN provides precision voltage-to-current conversion with rail-to-rail output swing that maximizes dynamic range. Its 1.8-6.0 V supply range supports both 3.3 V digital-mixed loops and 5 V legacy industrial instrumentation. The ±150 µV maximum offset ensures accurate loop-current scaling for ADC measurement, while the 110 µA Iq minimizes error from supply loading. The dual op amp can implement both the current-loop driver and the receiver-side voltage follower in a single chip, simplifying BOM and PCB layout. Use 0.1% sense resistors and add protection diodes against loop transients.
추천
Automotive Sensor Interfaces
The MCP6072T-E/SN tape-and-reel variant is qualified to AEC-Q100 standards and operates from -40°C to +125°C, making it suitable for automotive sensor interfaces including temperature, pressure, and position sensing. Its rail-to-rail input/output handles single-supply 5 V automotive rails, while the ±150 µV offset preserves accuracy for low-level analog signals. The 1.2 MHz GBW and 0.5 V/µs slew rate accommodate automotive sensor bandwidths (typically <50 kHz) without distortion. The dual channel enables two independent sensor channels per IC, reducing BOM cost in body-control and powertrain modules. Follow automotive EMC practices: add input protection, isolated grounds, and proper PCB shielding.

설계 노트
Place a 0.1 µF X7R ceramic decoupling capacitor as close as possible to the V+ pin (pin 8), with the ground-side via directly under the device GND pad. For multi-channel applications, use a single shared bypass cap for both channels if traces are <5 mm; otherwise use two separate caps to minimize crosstalk. Avoid routing switching converter supplies near V+ to prevent supply ripple coupling.
The MCP6072 is rated for inputs within the supply rails. Driving the input beyond V+ by more than 300 mV can damage the ESD diodes; use a series input resistor (≥10 kΩ) and external clamp diodes if your source can exceed the rails (e.g., transients in industrial environments). For unity-gain buffer configurations, avoid capacitive loads above 100 pF directly at the output - add a 50-100 Ω series resistor for isolation.
Use a small ground plane under the SOIC-8 to provide thermal dissipation and a low-impedance return for high-frequency signals. Keep input traces short and routed as a differential pair for high-gain (>10) configurations to minimize pickup. Place the gain-setting feedback resistors within 3 mm of the inverting input pin to reduce parasitic capacitance that can degrade phase margin at high frequencies.
Estimated: at V+ = 5 V, Iq = 220 µA total, the dual op amp dissipates ~1.1 mW. The 8-pin SOIC has a θJA of ~160 °C/W, producing a junction temperature rise of ~0.18 °C above ambient - negligible. However, in a sealed enclosure with no airflow at 85 °C ambient, derate by ensuring the part never exceeds its 125 °C junction temperature limit.
