Key Features
- Ultra-low input bias current of 0.0001 µA at 25°C (100 pA) minimizes errors in high-impedance sensor interface circuits
- 74 dB minimum CMRR (91 dB typical) ensures excellent rejection of common-mode noise in differential measurement paths
- Single-supply voltage operation with rail-to-rail output swing maximizes dynamic range in low-voltage 2.7V to 5.5V systems
- SOIC-8 package provides 8 pins for standard layout with dual or single op-amp configurations on one PCB footprint
Applications
The MCP6071-E/SN is well-suited for precision analog signal conditioning in data acquisition front ends, portable medical instruments, and battery-powered sensor nodes where low offset voltage and minimal bias current are essential. Its 74 dB CMRR and voltage-feedback architecture make it effective in differential amplifier topologies measuring small signals from bridge sensors, thermocouples, or photodetectors. The rail-to-rail output capability allows full use of the ADC input range in single 3.3V or 5V supply systems.

Frequently Asked Questions
What is the input bias current of MCP6071-E/SN at room temperature and why does it matter for high-impedance sensors?
The MCP6071-E/SN has a maximum input bias current of 0.0001 µA (100 pA) at 25°C. With a 10 MΩ source impedance, this bias current introduces only 1 mV of offset error, making the device suitable for pH electrodes, photodiodes, and other high-impedance transducers where a standard bipolar op-amp with nanoampere bias current would cause unacceptable measurement errors.
What gain-bandwidth product does MCP6071-E/SN offer and up to what closed-loop bandwidth is it practical?
The MCP6071-E/SN has a gain-bandwidth product of approximately 1.2 MHz. At a closed-loop gain of 10 V/V (20 dB), the usable signal bandwidth is approximately 120 kHz, which is sufficient for audio signal processing, low-frequency vibration monitoring, and industrial 4–20 mA transmitter analog front ends operating below 10 kHz.
How does the 91 dB typical CMRR of MCP6071-E/SN benefit a Wheatstone bridge measurement circuit?
A Wheatstone bridge presents a small differential signal of a few millivolts on top of a large common-mode voltage equal to roughly half the supply, typically 1.5V to 2.5V. The MCP6071-E/SN's 91 dB typical CMRR attenuates this common-mode component by a factor greater than 35,000:1, ensuring the amplified output represents the true bridge imbalance rather than supply-voltage artifacts.
Can MCP6071-E/SN operate from a single 3.3V supply in a microcontroller-based system, and what output swing is achievable?
Yes, the MCP6071-E/SN operates from a single supply voltage as low as 2.7V to 5.5V, making it directly compatible with 3.3V MCU systems. With a rail-to-rail output stage, it swings within approximately 25 mV of both the positive and negative supply rails at light loads, delivering usable output voltages from about 25 mV to 3.275V on a 3.3V supply.
