Key Features
- 35 MHz gain-bandwidth product enables high-speed differential signal amplification for sensor front ends running at gains of 10 to 100
- 88 dB CMRR (minimum 62 dB over temperature) suppresses power-line noise and ground offsets in bridge transducer and ECG circuits
- Wide 1.8 V to 5.5 V supply range supports both single-cell Li-Ion and 5 V logic systems without level shifting
- 5 nA maximum bias current (0.005 µA) protects high-impedance sources such as pH electrodes and piezoelectric sensors from loading errors
Applications
MCP6N11-100E/SN is designed for precision differential signal conditioning from Wheatstone bridges, strain gauges, and thermocouple amplifiers where 88 dB CMRR is needed to reject common-mode industrial noise up to 35 MHz. Its low 5 nA input bias current and 3 mV maximum offset voltage suit medical biosignal front ends such as ECG and EMG amplifiers powered from single 3.3 V or 5 V rails. The SOIC-8 package integrates easily into portable diagnostic and industrial process-control instrument designs.

Frequently Asked Questions
At a gain of 100, what usable signal bandwidth does MCP6N11-100E/SN provide given its 35 MHz GBW?
With a 35 MHz gain-bandwidth product, the MCP6N11-100E/SN achieves a -3 dB bandwidth of approximately 350 kHz at a gain of 100. This is sufficient for industrial vibration monitoring up to 200 kHz and for audio-frequency biomedical signals such as EMG (up to 10 kHz) or ECG (up to 1 kHz) with substantial margin.
How does MCP6N11-100E/SN's CMRR performance help in a 4-wire load-cell weighing application?
A 4-wire load cell mounted near a switching power supply can see common-mode noise of 100 mV or more at 50 Hz or 60 Hz. The MCP6N11-100E/SN's 88 dB CMRR attenuates that 100 mV by a factor exceeding 79,000, leaving less than 1.3 µV of common-mode artifact at the output — well below the 3 mV input offset voltage — enabling sub-milligram weight resolution when combined with a 24-bit ADC.
What supply voltage flexibility does MCP6N11-100E/SN offer for a portable medical device running on a 3.7 V Li-Ion cell?
The device operates from a single supply between 1.8 V and 5.5 V, making it directly compatible with a 3.7 V Li-Ion cell throughout its discharge cycle from 4.2 V down to 3.0 V. No secondary regulated rail is required for the instrumentation amplifier stage, reducing the BOM and quiescent current draw compared to designs that need a 5 V boost converter for the analog front end.
When would MCP6N11-100E/SN be preferred over a discrete three-op-amp instrumentation amplifier topology?
A discrete three-op-amp INA requires 3 matched op-amps, 7 precision resistors (0.01% tolerance or better), and careful PCB layout to achieve 80 dB CMRR. MCP6N11-100E/SN integrates all gain-setting circuitry in a single SOIC-8 package, reducing component count from roughly 10 parts to 1 (plus a single external gain resistor), and its factory-trimmed matching typically outperforms discrete resistor networks, especially above 10 kHz.
