What are the key features of MCP6271T-E/OT?
- 2 MHz gain-bandwidth product enabling active filter and signal conditioning stages up to audio and low-RF frequencies
- Rail-to-rail input and output operation from 1.8 V to 6 V maximizing dynamic range in single-supply low-voltage designs
- Ultra-low input bias current of 5 nA maximum for accurate interfacing with high-impedance piezoelectric and resistive sensors
- 85 dB typical CMRR (65 dB minimum) suppressing power-supply and common-mode noise in precision differential signal chains
- Compact 5-pin SOT-23 package enabling space-efficient single-amplifier placements on crowded mixed-signal PCBs
What is MCP6271T-E/OT used for?
The MCP6271T-E/OT is used in single-supply portable instruments, IoT sensor nodes, and wearable electronics where a compact 2 MHz op-amp with rail-to-rail I/O is needed in the smallest possible package. It serves as a gain stage or active low-pass filter for MEMS microphone, pressure sensor, and thermopile signal chains operating at 3.3 V. Its low input bias current of 5 nA also makes it suitable for transimpedance amplifier (TIA) stages in optical proximity detectors and smoke sensors.

Frequently Asked Questions
What gain-bandwidth product does the MCP6271T-E/OT offer and which filter applications can it support?
The MCP6271T-E/OT has a 2 MHz gain-bandwidth product, supporting active low-pass, band-pass, or high-pass filter stages with corner frequencies up to tens of kilohertz at unity gain, suitable for audio processing, sensor anti-aliasing, and low-frequency signal reconstruction.
How does the MCP6271T-E/OT compare to its dual-channel sibling MCP6042 in terms of channel count and package size?
The MCP6271T-E/OT is a single-channel device in a 5-pin SOT-23 package, making it roughly half the PCB area of the dual-channel MCP6042 in an MSOP-8. Designers select MCP6271T when only 1 amplifier stage is needed and board space is more critical than minimizing component count.
What supply voltage range and input bias current specification make the MCP6271T-E/OT suitable for battery-powered sensor circuits?
The MCP6271T-E/OT operates from 1.8 V to 6 V, covering lithium coin cell, alkaline, and Li-ion battery voltages. Its maximum input bias current of 5 nA (0.005 µA) minimizes offset errors when connected to high-impedance chemical or optical sensors in handheld devices.
What CMRR performance does the MCP6271T-E/OT achieve and how does it benefit noisy industrial environments?
The MCP6271T-E/OT achieves a typical CMRR of 85 dB and a minimum of 65 dB, rejecting common-mode interference from power lines, switching regulators, and ground noise by a factor exceeding 1700x, which is important for accurate sensor readings on electrically noisy PCBs or near motor drives.
